Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The summary of our significant accounting policies is presented below to assist in evaluating our consolidated financial statements. PRINCIPLES OF CONSOLIDATION The consolidated financial statements include our accounts and those of our subsidiaries in which we have a controlling interest. All significant intercompany balances and transactions are eliminated. USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS In preparing our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP), we make judgments and estimates about the amounts reflected in our consolidated financial statements. As part of our financial reporting process, our management collaborates to determine the necessary information on which to base our judgments and develop estimates used to prepare the consolidated financial statements. We use historical experience and available information to make these judgments and estimates. However, different amounts could be reported using different assumptions and in light of different facts and circumstances. Therefore, actual amounts could differ from the estimates reflected in our consolidated financial statements. CASH AND CASH EQUIVALENTS Cash investments having original maturities of three months or less are considered cash equivalents. Cash equivalents principally consist of investments in money market funds and bank deposits at June 30, 2021. ACCOUNTS RECEIVABLE We market our products to a diverse customer base throughout the world. Trade credit is extended based upon periodically updated evaluations of each customer’s ability to satisfy its obligations. We make judgments as to our ability to collect outstanding receivables and provide allowances for the portion of receivables when collection becomes doubtful. Accounts receivable reserves are determined based upon an aging of accounts and a review of specific accounts. INVENTORIES We use the last-in, first-out (LIFO) method for determining the cost of a significant portion of our United States (U.S.) inventories, and they are stated at the lower of cost or market. The cost of the remainder of our inventories is measured using approximate costs determined on the first-in, first-out basis or using the average cost method, and are stated at the lower of cost or net realizable value. When market conditions indicate an excess of carrying costs over market value, a lower of cost or net realizable value provision or a lower of cost or market provision, as applicable, is recorded. Once inventory is determined to be excess or obsolete, a new cost basis is established that is not subsequently written back up in future periods. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are carried at cost. Major improvements are capitalized, while maintenance and repairs are expensed as incurred. Retirements and disposals are removed from cost and accumulated depreciation accounts, with the gain or loss reflected in operating income. Interest related to the construction of major facilities is capitalized as part of the construction costs and is depreciated over the facilities' estimated useful lives. Depreciation for financial reporting purposes is computed using the straight-line method over the following estimated useful lives: building and improvements over 15-40 years; machinery and equipment over 4-15 years; furniture and fixtures over 5-10 years and computer hardware and software over 3-5 years. LONG-LIVED ASSETS We evaluate the recoverability of property, plant and equipment, operating lease right-of-use (ROU) assets and intangible assets that are amortized, whenever events or changes in circumstances indicate the carrying amount of any such assets may not be fully recoverable. Changes in circumstances include technological advances, changes in our business model, capital structure, economic conditions or operating performance. Our evaluation is performed at the asset group level, based upon, among other things, our assumptions about the estimated future undiscounted cash flows these assets are expected to generate. When the sum of the undiscounted cash flows is less than the carrying value, we will recognize an impairment loss to the extent that carrying value exceeds fair value. We apply our best judgment when performing these evaluations to determine if a triggering event has occurred, the undiscounted cash flows used to assess recoverability and the fair value of the asset group. GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill represents the excess of cost over the fair value of the net assets of acquired companies. Goodwill and other intangible assets with indefinite lives are tested at least annually for impairment. We perform our annual impairment tests during the June quarter in connection with our annual planning process unless there are impairment indicators based on the results of an ongoing cumulative qualitative assessment that warrant a test prior to that quarter. We evaluate the recoverability of goodwill for each of our reporting units by comparing the fair value of each reporting unit with its carrying value. The fair values of our reporting units are determined using a combination of a discounted cash flow analysis and market multiples based upon historical and projected financial information. We apply our best judgment when assessing the reasonableness of the financial projections used to determine the fair value of each reporting unit. We evaluate the recoverability of indefinite-lived intangible assets using a discounted cash flow analysis based on projected financial information. This evaluation is sensitive to changes in market interest rates and other external factors. The majority of our intangible assets with definite lives are amortized on a straight-line basis, while certain customer-related intangible assets are amortized on an accelerated method. Identifiable assets with finite lives are reviewed for impairment when events or circumstances indicate that the carrying value may not be recoverable. PENSION AND OTHER POSTRETIREMENT BENEFITS We sponsor these types of benefit plans for certain employees and retirees. Accounting for the cost of these plans requires the estimation of the cost of the benefits to be provided well into the future and attributing that cost over either the expected work life of employees or over average life of participants participating in these plans, depending on plan status and on participant population. This estimation requires our judgment about the discount rate used to determine these obligations, expected return on plan assets, rate of future compensation increases, rate of future health care costs, withdrawal and mortality rates and participant retirement age. Differences between our estimates and actual results may significantly affect the cost of our obligations under these plans. In the valuation of our pension and other postretirement benefit liabilities, management utilizes various assumptions. Discount rates are derived by identifying a theoretical settlement portfolio of high quality corporate bonds sufficient to provide for a plan’s projected benefit payments. This rate can fluctuate based on changes in the corporate bond yields. The long-term rate of return on plan assets is estimated based on an evaluation of historical returns for each asset category held by the plans, coupled with the current and short-term mix of the investment portfolio. The historical returns are adjusted for expected future market and economic changes. This return will fluctuate based on actual market returns and other economic factors. The rate of future health care costs is based on historical claims and enrollment information projected over the next year and adjusted for administrative charges. This rate is expected to decrease until 2027. Future compensation rates, withdrawal rates and participant retirement age are determined based on historical information. These assumptions are not expected to significantly change. Mortality rates are determined based on a review of published mortality tables. EARNINGS PER SHARE Basic earnings per share is computed using the weighted average number of shares outstanding during the period, while diluted earnings per share is calculated to reflect the potential dilution that would occur related to the issuance of capital stock under stock option grants, performance awards and restricted stock units. The difference between basic and diluted earnings per share relates solely to the effect of capital stock options, performance awards and restricted stock units. The following tables provide the computation of diluted shares outstanding: (in thousands) 2021 2019 Weighted-average shares outstanding during period 83,602 82,379 Add: Unexercised stock options and unvested restricted stock units 731 912 Number of shares on which diluted earnings per share is calculated 84,333 83,291 Unexercised stock options with an exercise price greater than the average market price and restricted stock units not included in the computation because they were anti-dilutive 295 427 In 2020, the effect of unexercised capital stock options, unvested performance awards and unvested restricted stock units was anti-dilutive as a result of a net loss in the period and therefore has been excluded from diluted shares outstanding as well as from the diluted earnings per share calculation. REVENUE RECOGNITION The Company's contracts with customers are comprised of purchase orders, and for larger customers, may also include long-term agreements. We account for a contract when it has approval and commitment from both parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable. These contracts with customers typically relate to the manufacturing of products, which represent single performance obligations that are satisfied when control of the product passes to the customer. The Company considers the timing of right to payment, transfer of risk and rewards, transfer of title, transfer of physical possession and customer acceptance when determining when control transfers to the customer. As a result, revenue is generally recognized at a point in time - either upon shipment or delivery - based on the specific shipping terms in the contract. The shipping terms vary across all businesses and depend on the product, customary local commercial terms and the type of transportation. Shipping and handling activities are accounted for as activities to fulfill a promise to transfer a product to a customer and as such, costs incurred are recorded when the related revenue is recognized. Payment for products is due within a limited time period after shipment or delivery, typically within 30 to 90 calendar days of the respective invoice dates. The Company does not generally offer extended payment terms. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. Amounts billed and due from our customers are classified as accounts receivable, less allowance for doubtful accounts on the consolidated balance sheets. Certain contracts with customers, primarily distributor customers, have an element of variable consideration that is estimated when revenue is recognized under the contract. Variable consideration primarily includes volume incentive rebates, which are based on achieving a certain level of purchases and other performance criteria as established by our distributor programs. These rebates are estimated based on projected sales to the customer and accrued as a reduction of net sales as they are earned. The majority of our products are consumed by our customers or end users in the manufacture of their products. Historically, we have experienced very low levels of returned products and do not consider the effect of returned products to be material. We have recorded an estimated returned goods allowance to provide for any potential returns. We warrant that products sold are free from defects in material and workmanship under normal use and service when correctly installed, used and maintained. This warranty terminates 30 days after delivery of the product to the customer and does not apply to products that have been subjected to misuse, abuse, neglect or improper storage, handling or maintenance. Products may be returned to Kennametal only after inspection and approval by Kennametal and upon receipt by the customer of shipping instructions from Kennametal. We have included an estimated allowance for warranty returns in our returned goods allowance discussed above. See "Note 21. Segment Data" for disaggregation of revenue by geography and end market. The Company records a contract asset when it has a right to payment from a customer that is conditioned on events that have occurred other than the passage of time. The Company also records a contract liability when customers prepay but the Company has not yet satisfied its performance obligation. The Company did not have any material remaining performance obligations, contract assets or liabilities as of June 30, 2021 and 2020. The Company pays sales commissions related to certain contracts, which qualify as incremental costs of obtaining a contract. However, the Company applies the practical expedient that allows an entity to recognize incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that would have been recognized is one year or less. These costs are recorded within operating expense in our consolidated statements of income. SHIPPING AND HANDLING FEES AND COSTS All fees billed to customers for shipping and handling are classified as a component of sales. All costs associated with shipping and handling are classified as a component of cost of goods sold. STOCK-BASED COMPENSATION We recognize stock-based compensation expense for all stock options, restricted stock awards and restricted stock units over the period from the date of grant to the date when the award is no longer contingent on the employee providing additional service (substantive vesting period), net of expected forfeitures. We utilize the Black-Scholes valuation method to establish the fair value of all stock option awards. Time vesting stock units are valued at the market value of the stock on the grant date. Performance vesting stock units with a market condition are valued using a Monte Carlo model. Capital stock options are granted to eligible employees at fair market value at the date of grant. Capital stock options are exercisable under specified conditions for up to 10 years from the date of grant. The Kennametal Inc. Stock and Incentive Plan of 2010, as Amended and Restated on October 22, 2013, and further amended on January 27, 2015 (A/R 2010 Plan), by the Kennametal Inc. 2016 Stock and Incentive Plan, and on October 27, 2020 by the Kennametal Inc. 2020 Stock and Incentive Plan (2020 Plan) authorize the issuance of up to 9,500,000 shares of the Company’s capital stock plus any shares remaining unissued under the Kennametal Inc. Stock and Incentive Plan of 2002, as amended (2002 Plan). Under the provisions of the A/R 2010 Plan and 2020 Plan participants may deliver stock, owned by the holder for at least six months, in payment of the option price and receive credit for the fair market value of the shares on the date of delivery. The fair market value of shares delivered during 2021, 2020 and 2019 was immaterial. In addition to stock option grants, the A/R 2010 Plan and the 2020 Plan permit the award of stock appreciation rights, performance share awards, performance unit awards, restricted stock awards, restricted unit awards and share awards to directors, officers and key employees. RESEARCH AND DEVELOPMENT COSTS Research and development costs of $39.5 million, $38.7 million and $39.0 million in 2021, 2020 and 2019, respectively, were expensed as incurred. These costs are included in operating expense in the consolidated statements of income. INCOME TAXES Deferred income taxes are recognized based on the future income tax effects (using enacted tax laws and rates) of differences in the carrying amounts of assets and liabilities for financial reporting and tax purposes. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not (greater than 50 percent) that a tax benefit will not be realized. In evaluating the need for a valuation allowance, we consider all potential sources of taxable income, including income available in carryback periods, future reversals of taxable temporary differences, projections of taxable income, and income from tax planning strategies, as well as all available positive and negative evidence. Positive evidence includes factors such as a history of profitable operations, and projections of future profitability within the carry forward period, including taxable income from tax planning strategies. Negative evidence includes items such as cumulative losses, projections of future losses, or carryforward periods that are not long enough to allow for the utilization of the deferred tax asset based on existing projections of income. Upon changes in facts and circumstances, we may conclude that deferred tax assets for which no valuation allowance is currently recorded may not be realized, resulting in a charge to establish a valuation allowance. Existing valuation allowances are re-examined under the same standards of positive and negative evidence. If it is determined that it is more likely than not that a deferred tax asset will be realized, the appropriate amount of the valuation allowance, if any, is released. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES As part of our financial risk management program, we use certain derivative financial instruments. We do not enter into derivative transactions for speculative purposes and, therefore, hold no derivative instruments for trading purposes. We use derivative financial instruments to provide predictability to the effects of changes in foreign exchange rates on our consolidated results. Our objective in managing foreign exchange exposures with derivative instruments is to reduce volatility in cash flow, allowing us to focus more of our attention on business operations. With respect to interest rate management, we use forward-starting interest rate swaps to effectively hedge the variability in future benchmark interest payments attributable to changes in interest rates on forecasted issuances of fixed-rate debt. We account for derivative instruments as a hedge of the related asset, liability, firm commitment or anticipated transaction, when the derivative is specifically designated as a hedge of such items. We measure hedge effectiveness by assessing the changes in the fair value or expected future cash flows of the hedged item. Certain currency forward contracts hedging significant cross-border intercompany loans are considered other derivatives and, therefore, do not qualify for hedge accounting. CASH FLOW HEDGES Currency Forward contracts and range forward contracts (a transaction where both a put option is purchased and a call option is sold) are designated as cash flow hedges and hedge anticipated cash flows from cross-border intercompany sales of products and services. Gains and losses realized on these contracts are recorded in accumulated other comprehensive loss, and are recognized as a component of other income, net when the underlying sale of products or services is recognized into earnings. Interest Rate Forward starting interest rate swap contracts are designated as cash flow hedges and hedge a portion of the interest rate risk related to anticipated issuances of debt. Gains and losses realized on these contracts are recorded in accumulated other comprehensive loss, and are recognized as a component of interest expense when the interest payments on the future debt interest are recognized into earnings. NET INVESTMENT HEDGES We designate financial instruments as net investment hedges from time to time to hedge the foreign exchange exposure of our net investment in foreign currency-based subsidiaries. The remeasurements of these non-derivatives designated as net investment hedges are calculated each period with changes reported in foreign currency translation adjustment within accumulated other comprehensive loss. Such amounts will remain in accumulated other comprehensive loss unless we complete or substantially complete liquidation or disposal of our investment in the underlying foreign operations. CURRENCY TRANSLATION Assets and liabilities of international operations are translated into U.S. dollars using year-end exchange rates, while revenues and expenses are translated at average exchange rates throughout the year. The resulting net translation adjustments are recorded as a component of accumulated other comprehensive loss. The local currency is the functional currency of most of our locations. Losses of $3.3 million, $3.4 million and $2.7 million from currency transactions were included in other income, net in 2021, 2020 and 2019, respectively. NEW ACCOUNTING STANDARDS Effective July 1, 2020, the Company adopted Accounting Standards Update (ASU) No. 2016-13, Financial Instruments – Credit Losses. This ASU added a new impairment model (known as the current expected credit loss (CECL) model) that is based on expected losses rather than incurred losses. The new guidance applies to all financial assets, including trade receivables. The Company adopted the ASU on a modified retrospective approach. Under this method of adoption, there was no cumulative-effect adjustment to beginning retained earnings on the consolidated balance sheets. Adoption of this standard did not have a material effect on the Company's consolidated financial statements.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy consists of three levels to prioritize the inputs used in valuations, as defined below: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3: Inputs that are unobservable. As of June 30, 2021, the fair values of the Company’s financial assets and financial liabilities measured at fair value on a recurring basis are categorized as follows: (in thousands) Level 1 Level 2 Level 3 Total Assets: Derivatives (1) $ — $ 36 $ — $ 36 Total assets at fair value $ — $ 36 $ — $ 36 Liabilities: Derivatives (1) $ — $ 87 $ — $ 87 Total liabilities at fair value $ — $ 87 $ — $ 87 As of June 30, 2020, the fair value of the Company’s financial assets and financial liabilities measured at fair value on a recurring basis are categorized as follows: (in thousands) Level 1 Level 2 Level 3 Total Assets: Derivatives (1) $ — $ 36 $ — $ 36 Total assets at fair value $ — $ 36 $ — $ 36 Liabilities: Derivatives (1) $ — $ 2,139 $ — $ 2,139 Total liabilities at fair value $ — $ 2,139 $ — $ 2,139 (1) Currency and interest rate derivatives are valued based on observable market spot and forward rates and are classified within Level 2 of the fair value hierarchy.

Leases [Abstract]
Lessee, Operating Leases	LEASES At the inception of our contracts we determine if the contract is or contains a lease. A contract is or contains a lease if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration. ROU assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term at commencement. For leases that do not have a readily determinable implicit rate, we use a discount rate based on our incremental borrowing rate, which is determined considering factors such as the lease term, our credit rating and the economic environment of the location of the lease as of the commencement date. We account for non-lease components separately from lease components. These costs often relate to the payments for a proportionate share of real estate taxes, insurance, common area maintenance and other operating costs in addition to base rent. We also do not recognize ROU assets and liabilities for leases with an initial term of 12 months or less. Lease costs associated with leases of less than 12 months were $2.4 million and $6.4 million for the years ended June 30, 2021 and 2020, respectively. As a lessee, we have various operating lease agreements primarily related to real estate, vehicles and office and plant equipment. Our real estate leases, which are comprised primarily of manufacturing, warehousing, office and administration facilities, represent a majority of our lease liability. Our lease payments are largely fixed. Any variable lease payments, including utilities, common area maintenance and repairs and maintenance, are expensed during the period incurred. Variable lease costs were immaterial for the year ended June 30, 2021 and 2020. A majority of our real estate leases include options to extend the lease and options to early terminate the lease. Leases with an early termination option generally involve a termination payment. We review all options to extend, terminate, or purchase the ROU assets at the inception of the lease and account for these options when they are reasonably certain of being exercised. Our lease agreements generally do not contain any material residual value guarantees or materially restrictive covenants. We do not have any material leases that have been signed but not commenced, and we did not have any lease transactions with related parties. Operating lease expense is recognized on a straight-line basis over the lease term and is included in operating expense on our consolidated statements of income. Operating lease cost was $20.2 million, $22.6 million and $26.6 million in 2021, 2020 and 2019, respectively. The following table sets forth supplemental balance sheet information related to our operating leases: Year Ended June 30, 2021 2020 Weighted average remaining lease term 8.0 years 8.6 years Weighted average discount rate 3.3 % 3.3 % The following table sets forth supplemental cash flow information related to our operating leases: Year Ended June 30, 2021 2020 Operating cash outflows from operating leases $ 17,651 $ 15,635 ROU assets obtained in exchange for new operating lease liabilities $ 17,235 $ 16,171 The following table sets forth the maturities of our operating lease liabilities and reconciles the respective undiscounted payments to the operating lease liabilities in the consolidated balance sheet as of June 30, 2021: Year Ended June 30, June 30, 2021 2022 $ 15,062 2023 11,466 2024 7,993 2025 5,346 2026 2,983 Thereafter 15,840 Total undiscounted operating lease payments $ 58,690 Less: discount to net present value 7,670 Total operating lease liabilities $ 51,020

Notes Payable and Lines of Credit	AND OTHER LINES OF CREDIT AND NOTES PAYABLE Credit Agreement During the three months ended September 30, 2020, we entered into the First Amendment (the Amendment) to the Fifth Amended and Restated Credit Agreement dated as of June 21, 2018, (as amended by the Amendment, the Credit Agreement). The Credit Agreement is a five The Credit Agreement requires us to comply with various restrictive and affirmative covenants, including two financial covenants: (1) a maximum leverage ratio where debt, net of domestic cash in excess of $25 million and sixty percent of the unrestricted cash held outside of the United States, must be less than or equal to 3.5 times trailing twelve months EBITDA (temporarily increased by the Amendment to 4.25 times trailing twelve months EBITDA during the period from September 30, 2020 through and including December 31, 2021), adjusted for certain non-cash expenses and which may be further adjusted, at our discretion, to include up to $120 million of cash restructuring charges through December 31, 2021; and (2) a minimum consolidated interest coverage ratio of EBITDA to interest of 3.5 times (as such terms are defined in the Credit Agreement). Borrowings under the Credit Agreement are guaranteed by our significant domestic subsidiaries. As of June 30, 2021, we were in compliance with all covenants of the Credit Agreement and we had no borrowings outstanding and $700.0 million of availability. There were $500.0 million borrowings outstanding as of June 30, 2020. The weighted average interest rate on borrowings under the Credit Agreement was 3.1 percent for the year ended June 30, 2021. Other lines of credit and notes payable were $8.4 million and $0.4 million at June 30, 2021 and 2020, respectively. The lines of credit represented short-term borrowings under credit lines with commercial banks in the various countries in which we operate. These credit lines, translated into U.S. dollars at June 30, 2021 exchange rates, totaled $65.0 million.

The CARES Act, among other things, allows net operating losses arising in taxable years beginning after December 31, 2017 and before January 1, 2021 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes; permits net operating loss carryovers and carrybacks to offset 100 percent of taxable income for taxable years beginning before January 1, 2021; and modifies the limitation on business interest by increasing the allowable business interest deduction from 30 percent of adjusted taxable income to 50 percent of adjusted taxable income for taxable years beginning in 2019 or 2020. We carried back our taxable loss in the U.S. for fiscal 2020 under the provisions of the CARES Act and recorded a benefit in our tax provision during fiscal 2020. Swiss tax reform Legislation was effectively enacted during the December quarter of fiscal 2020 when the Canton of Schaffhausen approved the Federal Act on Tax Reform and AHV Financing on October 8, 2019 (Swiss tax reform). Significant changes from Swiss tax reform include the abolishment of certain favorable tax regimes and the creation of a multi-year transitional period at both the federal and cantonal levels. The transitional provisions of Swiss tax reform allow companies to utilize a combination of lower tax rates and tax basis adjustments to fair value, which are used for tax depreciation and amortization purposes resulting in deductions over the transitional period. To reflect the federal and cantonal transitional provisions, as they apply to us, we recorded a deferred tax asset of $14.5 million during the December quarter of fiscal 2020. We consider the deferred tax asset from Swiss tax reform to be an estimate based on our current interpretation of the legislation, which is subject to change based on further legislative guidance, review with the Swiss federal and cantonal authorities, and modifications to the underlying valuation. We anticipate finalization of the deferred tax asset within the next twelve months. The reconciliation of income taxes computed using the statutory U.S. income tax rate and the provision for income taxes was as follows for the years ended June 30: (in thousands) 2021 2020 2019 Income taxes at U.S. statutory rate $ 13,579 $ 412 $ 65,359 State income taxes, net of federal tax benefit (1,725) 1,283 289 U.S. income taxes provided on international income (6,479) 12,422 7,347 Combined tax effects of international income 5,860 10,583 162 Impact of goodwill impairment charges — 5,651 — Change in valuation allowance and other uncertain tax positions 1,127 755 (1,473) U.S. research and development credit (3,055) (4,093) (3,911) Change in permanent reinvestment assertion — — 6,093 Combined effects of U.S. tax reform — — (9,280) Combined effects of Swiss tax reform — (14,500) — Combined effects of the U.S. CARES Act — (6,913) — Recognition of stranded deferred tax balance (3,465) — — Other 401 1,407 (1,227) Provision for income taxes $ 6,243 $ 7,007 $ 63,359 During 2021, we recorded a tax benefit of $3.5 million for the recognition of a stranded deferred tax balance in accumulated other comprehensive loss associated with the forward starting interest rate swap contracts that were terminated when the 2022 Senior Notes were extinguished. The impact of this item is included in the tax reconciliation table under the caption “Recognition of stranded deferred tax balance” and in the consolidated statements of cash flows as a non-cash item within the caption "Debt refinancing charge." During 2021, we recorded a net tax benefit of $9.3 million related to a tax election made in our fiscal 2020 U.S. income tax return pursuant to global intangible low-taxed income (GILTI) regulations which were issued during the current fiscal year. The impact of this item is included in the tax reconciliation table under the caption “U.S. income taxes provided on international income.” During 2019, we recorded a net tax benefit of $9.3 million associated with the finalization of our toll tax charge which included a benefit of $14.5 million for the toll tax charge and a $5.3 million charge for an unrecognized tax benefit. The effect of these items is included in the tax reconciliation table under the caption “Combined effects of U.S. tax reform.” During 2019, we released a $1.1 million valuation allowance that was previously recorded against the net deferred tax assets of our Australian subsidiary. The effect of this item is included in the tax reconciliation table under the caption “Change in valuation allowance and other uncertain tax positions.” The components of net deferred tax assets and liabilities were as follows at June 30: (in thousands) 2021 2020 Deferred tax assets: Net operating loss (NOL) carryforwards $ 44,258 $ 31,891 Inventory valuation and reserves 11,068 8,220 Pension benefits 7,136 19,608 Other postretirement benefits 3,486 4,110 Accrued employee benefits 11,168 11,650 Operating lease liabilities 12,652 11,889 Other accrued liabilities 15,596 7,310 Tax credits and other carryforwards 32,490 21,048 Intangible assets 7,784 10,531 Other — 364 Total 145,638 126,621 Valuation allowance 21,263 16,654 Total deferred tax assets $ 124,375 $ 109,967 Deferred tax liabilities: Tax depreciation in excess of book $ 63,020 $ 67,411 Operating lease right-of-use assets 12,502 11,715 Unremitted earnings not permanently reinvested 6,429 5,855 Other $ 7,392 — Total deferred tax liabilities $ 89,343 $ 84,981 Total net deferred tax assets (liabilities) $ 35,032 $ 24,986 As of June 30, 2021, we have $26.3 million of U.S. net deferred tax assets. Within this amount is $57.0 million related to net operating loss, tax credit, and other carryforwards that can be used to offset future U.S. taxable income. Certain of these carryforwards will expire if they are not used within a specified timeframe. At this time, we consider it more likely than not that we will have sufficient U.S. taxable income in the future that will allow us to realize these net deferred tax assets. However, it is possible that some or all of these tax attributes could ultimately expire unused, especially if our end markets do not continue to recover from the COVID-19 global pandemic. Therefore, if we are unable to generate sufficient U.S. taxable income from our operations, a valuation allowance to reduce the U.S. net deferred tax assets may be required, which would materially increase income tax expense in the period in which the valuation allowance is recorded. Included in deferred tax assets at June 30, 2021 is $32.5 million associated with tax credits and other carryforward items in the U.S. Of that amount, $0.7 million expires through 2031, $4.6 million expires through 2036, $18.3 million expires through 2041, $2.6 million does not expire, and $6.3 million is amortizable over eight years. Included in deferred tax assets at June 30, 2021 is $44.3 million associated with NOL carryforwards in U.S. federal, state and foreign jurisdictions. Of that amount, $8.1 million expires through 2026, $2.2 million expires through 2031, $2.7 million expires through 2036, $3.8 million expires through 2041, and the remaining $27.5 million does not expire. The realization of these tax benefits is primarily dependent on future taxable income in these jurisdictions. A valuation allowance of $21.3 million has been placed against deferred tax assets primarily in U.S. state, Brazil and Bolivia jurisdictions, all of which would be allocated to income tax expense upon realization of the deferred tax assets. As the respective operations generate sufficient income, the valuation allowances will be partially or fully reversed at such time we believe it will be more likely than not that the deferred tax assets will be realized. In 2021, the valuation allowance related to these deferred tax assets increased by $4.6 million. We consider the majority of the $1.5 billion unremitted earnings of our non-U.S. subsidiaries to be permanently reinvested. With regard to these unremitted earnings, we have not, nor do we anticipate the need to, repatriate funds to the U.S. to satisfy domestic liquidity needs arising in the ordinary course of business, including liquidity needs associated with our domestic debt service requirements. Determination of the amount of unrecognized deferred tax liability related to indefinitely reinvested earnings is not practicable due to our legal entity structure and the complexity of U.S. and local tax laws. With regard to the small portion of unremitted earnings that are not indefinitely reinvested, we maintain a deferred tax liability for foreign withholding and U.S. state income taxes. The deferred tax liability associated with unremitted earnings of our non-U.S. subsidiaries not permanently reinvested is $6.4 million as of June 30, 2021. A reconciliation of the beginning and ending amount of unrecognized tax benefits (excluding interest and penalty) is as follows as of June 30: (in thousands) 2021 2020 2019 Balance at beginning of year $ 8,680 $ 8,952 $ 5,775 Increases for tax positions of prior years — — 7,384 Decreases related to settlement with taxing authority — — (3,765) Decreases related to lapse of statute of limitations (229) (214) (324) Foreign currency translation 205 (58) (118) Balance at end of year $ 8,656 $ 8,680 $ 8,952 The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate in 2021, 2020 and 2019 is $8.7 million, $8.7 million and $9.0 million, respectively. We believe that it is reasonably possible that the amount of unrecognized tax benefits will decrease by approximately $5.3 million within the next twelve months. Our policy is to recognize interest and penalties related to income taxes as a component of the provision for income taxes in the consolidated statements of income. We recognized a decrease of $0.2 million and $0.4 million in 2021 and 2019, respectively, and an increase of $1.0 million in 2020. As of June 30, 2021 and 2020, the amount of interest accrued was $1.4 million and $1.2 million, respectively. As of June 30, 2021 there was no penalty accrued and at June 30, 2020, the amount of penalty accrued was $0.5 million.

Retirement Benefits [Abstract]
Pension and Other Postretirement Benefits Disclosure	PENSION AND OTHER POSTRETIREMENT BENEFITS Defined Benefit Pension Plans We have defined benefit pension plans that cover certain employees in the U.S., Germany, the UK, Switzerland, Canada and Israel. Pension benefits under defined benefit pension plans are based on years of service and, for certain plans, on average compensation for specified years preceding retirement. We fund pension costs in accordance with the funding requirements of the Employee Retirement Income Security Act of 1974 (ERISA), as amended, for U.S. plans and in accordance with local regulations or customs for non-U.S. plans. The accrued benefit for all participants in the Kennametal Inc. Retirement Income Plan was frozen as of December 31, 2016. The majority of our defined benefit pension plans are closed to future participation. We have an Executive Retirement Plan for certain executives and a Supplemental Executive Retirement Plan both of which have been closed to future participation on June 15, 2017 and July 26, 2006, respectively. We presently provide varying levels of postretirement health care and life insurance benefits to certain employees and retirees. By fiscal 2019, participants over the age of 65 were transitioned to a private exchange and some received a fixed Health Retirement Account (HRA) contribution to offset the cost of their coverage. Postretirement health and life benefits are closed to future participants as of December 31, 2016. We use a June 30 measurement date for all of our plans. During fiscal 2021, as part of the plan to wind-up the fully frozen, overfunded Canadian defined benefit pension plans, the Company purchased an upfront annuity for retirees resulting in a non-cash settlement charge of $2.8 million. The Company expects to complete the wind-up of the Canadian plans by fiscal 2023. The funded status of our pension plans and amounts recognized in the consolidated balance sheets as of June 30 were as follows: (in thousands) 2021 2020 Change in benefit obligation: Benefit obligation, beginning of year $ 1,004,005 $ 964,741 Service cost 1,685 1,796 Interest cost 23,188 27,320 Participant contributions 548 637 Actuarial (gains) losses (16,794) 67,403 Benefits and expenses paid (52,719) (50,733) Currency translation adjustments 23,276 (5,758) Plan amendments (129) (231) Plan settlements (13,966) (1,286) Plan curtailments (10) (171) Other adjustments (359) 287 Benefit obligation, end of year $ 968,725 $ 1,004,005 Change in plans' assets: Fair value of plans' assets, beginning of year $ 876,036 $ 825,869 Actual return on plans' assets 54,026 96,133 Company contributions 9,998 9,721 Participant contributions 548 637 Plan settlements (13,966) (1,286) Benefits and expenses paid (52,719) (50,733) Currency translation adjustments 16,032 (4,305) Other adjustments 149 $ — Fair value of plans' assets, end of year $ 890,104 $ 876,036 Funded status of plans $ (78,621) $ (127,969) Amounts recognized in the balance sheets consist of: Long-term prepaid benefit $ 89,233 $ 43,116 Short-term accrued benefit obligation (6,918) (6,639) Accrued pension benefits (160,936) (164,446) Net amount recognized $ (78,621) $ (127,969) The pre-tax amounts related to our defined benefit pension plans recognized in accumulated other comprehensive loss were as follows at June 30: (in thousands) 2021 2020 Unrecognized net actuarial losses $ 279,628 $ 305,903 Unrecognized net prior service costs 2,001 2,026 Unrecognized transition obligations 277 332 Total $ 281,906 $ 308,261 To the best of our knowledge and belief, the asset portfolios of our defined benefit pension plans do not contain our capital stock. Apart from the partial annuitization of the Canadian plans as previously mentioned, we do not issue insurance contracts to cover future annual benefits of defined benefit pension plan participants. Transactions between us and our defined benefit pension plans include the reimbursement of plan expenditures incurred by us on behalf of the plans. To the best of our knowledge and belief, the reimbursement of cost is permissible under current ERISA rules or local government law. The accumulated benefit obligation for all defined benefit pension plans was $967.5 million and $1,001.8 million as of June 30, 2021 and 2020, respectively. Included in the above information are plans with accumulated benefit obligations exceeding the fair value of plan assets as of June 30 as follows: (in thousands) 2021 2020 Projected benefit obligation $ 174,973 $ 180,388 Accumulated benefit obligation 173,684 178,195 Fair value of plan assets 7,116 9,273 The components of net periodic pension income include the following as of June 30: (in thousands) 2021 2020 2019 Service cost $ 1,685 $ 1,796 $ 1,627 Interest cost 23,188 27,320 31,901 Expected return on plans' assets (53,653) (53,943) (53,789) Amortization of transition obligation 94 88 91 Amortization of prior service cost 34 50 (19) Curtailment (7) (115) — Settlement 3,190 (51) — Recognition of actuarial losses 13,606 10,359 6,723 Other adjustments (473) 288 — Net periodic pension income $ (12,336) $ (14,208) $ (13,466) As of June 30, 2021, the projected benefit payments, including future service accruals for these plans for 2022 through 2026, are $53.1 million, $53.0 million, $55.0 million, $55.5 million and $55.4 million, respectively, and $268.3 million in 2027 through 2031. The amounts of accumulated other comprehensive loss expected to be recognized in net periodic pension cost during 2022 related to net actuarial losses are $11.9 million. The amount of accumulated other comprehensive income expected to be recognized in net periodic pension cost during 2022 related to transition obligations and prior service cost is immaterial. We expect to contribute approximately $8 million to our pension plans in 2022, which is primarily for international plans. Other Postretirement Benefit Plans The funded status of our other postretirement benefit plans and the related amounts recognized in the consolidated balance sheets were as follows: (in thousands) 2021 2020 Change in benefit obligation: Benefit obligation, beginning of year $ 12,365 $ 12,642 Interest cost 307 404 Actuarial losses 60 709 Benefits paid (1,281) (1,390) Other (68) — Benefit obligation, end of year $ 11,383 $ 12,365 Funded status of plan $ (11,383) $ (12,365) Amounts recognized in the balance sheets consist of: Short-term accrued benefit obligation $ (1,252) $ (1,353) Accrued postretirement benefits (10,131) (11,012) Net amount recognized $ (11,383) $ (12,365) The pre-tax amounts related to our other postretirement benefit plans which were recognized in accumulated other comprehensive loss were as follows at June 30: (in thousands) 2021 2020 Unrecognized net actuarial losses $ 4,355 $ 4,602 Unrecognized net prior service credits (1,924) (2,200) Total $ 2,431 $ 2,402 The components of net periodic other postretirement benefit cost include the following for the years ended June 30: (in thousands) 2021 2020 2019 Interest cost $ 307 $ 404 $ 613 Amortization of prior service credit (276) (276) (90) Recognition of actuarial loss 307 257 248 Net periodic other postretirement benefit cost $ 338 $ 385 $ 771 As of June 30, 2021, the projected benefit payments, including future service accruals for our other postretirement benefit plans for 2022 through 2026, are $1.3 million, $1.2 million, $1.1 million, $1.0 million and $0.9 million, respectively, and $3.6 million in 2027 through 2031. The amounts of accumulated other comprehensive loss expected to be recognized in net periodic pension cost during 2022 related to net actuarial losses and related to prior service credit are costs of $0.3 million and income of $0.3 million, respectively. We expect to contribute approximately $1.3 million to our other postretirement benefit plans in 2022. The service cost component of net periodic pension income of $1.7 million, $1.8 million and $1.6 million for 2021, 2020 and 2019, respectively, was reported as a component of cost of goods sold and operating expense. The other components of net periodic pension income and net periodic other postretirement benefit cost totaling a net benefit of $13.7 million, $15.6 million and $14.3 million for 2021, 2020 and 2019, respectively, were presented as a component of other income, net. Assumptions The significant actuarial assumptions used to determine the present value of net benefit obligations for our defined benefit pension plans and other postretirement benefit plans were as follows: 2021 2020 2019 Discount Rate: U.S. plans 1.2-3.0% 1.6-2.9% 2.7-3.6% International plans 0.3-3.2% 0.2-2.4% 0.4-2.9% Rates of future salary increases: U.S. plans (Executive Retirement Plan only) 4.0 % 4.0 % 4.0 % International plans 1.5 % 1.5 % 1.8-3.0% The significant assumptions used to determine the net periodic income for our pension and other postretirement benefit plans were as follows: 2021 2020 2019 Discount Rate: U.S. plans 1.2-3.0% 2.7-3.6% 4.0-4.3% International plans 0.3-3.2% 0.4-2.9% 1.8-3.3% Rates of future salary increases: U.S. plans (Executive Retirement Plan only) 4.0 % 4.0 % 4.0 % International plans 1.5 % 1.8-3.0% 2.5-3.0% Rate of return on plans assets: U.S. plans 6.8 % 7.0 % 7.0 % International plans 0.2-5.3% 0.4-5.3% 5.0-5.3% The rates of return on plan assets are based on historical performance, as well as future expected returns by asset class considering macroeconomic conditions, current portfolio mix, long-term investment strategy and other available relevant information. The annual assumed rate of increase in the per capita cost of covered benefits (the health care cost trend rate) for our postretirement benefit plans was as follows: 2021 2020 2019 Health care costs trend rate assumed for next year 6.5 % 6.8 % 7.0 % Rate to which the cost trend rate gradually declines 5.0 % 5.0 % 5.0 % Year that the rate reaches the rate at which it is assumed to remain 2027 2027 2027 A change of one percentage point in the assumed health care cost trend rates would have an immaterial effect on both the total service and interest cost components of our other postretirement cost and other postretirement benefit obligation at June 30, 2021. Plan Assets The primary objective of certain of our pension plans' investment policies is to ensure that sufficient assets are available to provide the benefit obligations at the time the obligations come due. The overall investment strategy for the defined benefit pension plans' assets combine considerations of preservation of principal and moderate risk-taking. The assumption of an acceptable level of risk is warranted in order to achieve satisfactory results consistent with the long-term objectives of the portfolio. Fixed income securities comprise a significant portion of the portfolio due to their plan-liability-matching characteristics and to address the plans' cash flow requirements. Additionally, diversification of investments within each asset class is utilized to further reduce the effect of losses in single investments. Investment management practices for U.S. defined benefit pension plans must comply with ERISA and all applicable regulations and rulings thereof. The use of derivative instruments is permitted where appropriate and necessary for achieving overall investment policy objectives. Currently, the use of derivative instruments is not significant when compared to the overall investment portfolio. The Company utilizes a liability driven investment strategy (LDI) for the assets of its U.S. defined benefit pension plans in order to reduce the volatility of the funded status of these plans and to meet the obligations at an acceptable cost over the long term. This LDI strategy entails modifying the asset allocation and duration of the assets of the plans to more closely match the liability profile of these plans. The asset reallocation involves increasing the fixed income allocation, reducing the equity component and adding alternative investments. Longer duration interest rate swaps have been utilized periodically in order to increase the overall duration of the asset portfolio to more closely match the liabilities. Our defined benefit pension plans’ asset allocations as of June 30, 2021 and 2020 and target allocations for 2022, by asset class, were as follows: 2021 2020 Target % Equity 20 % 22 % 20 % Fixed Income 76 % 75 % 80 % Other 4 % 3 % — % The following sections describe the valuation methodologies used by the trustee to measure the fair value of the defined benefit pension plan assets, including an indication of the level in the fair value hierarchy in which each type of asset is generally classified (see Note 5 for the definition of fair value and a description of the fair value hierarchy). Corporate fixed income securities Investments in corporate fixed income securities consist of corporate debt and asset backed securities. These investments are classified as level two and are valued using independent observable market inputs such as the treasury curve, swap curve and yield curve. Common stock Common stocks are classified as level one and are valued at their quoted market price. Government securities Investments in government securities consist of fixed income securities such as U.S. government and agency obligations and foreign government bonds and asset and mortgage backed securities such as obligations issued by government sponsored organizations. These investments are classified as level two and are valued using independent observable market inputs such as the treasury curve, credit spreads and interest rates. Other fixed income securities Investments in other fixed income securities are classified as level two and valued based on observable market data. Other Other investments consist primarily of state and local obligations and short term investments including cash, corporate notes, and various short term debt instruments which can be redeemed within a nominal redemption notice period. These investments are primarily classified as level two and are valued using independent observable market inputs. The fair value methods described may not be reflective of future fair values. Additionally, while the Company believes the valuation methods used by the plans’ trustee are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in different fair value measurement at the reporting date. The following table presents the fair value of the benefit plans' assets by asset category as of June 30, 2021: (in thousands) Level 1 Level 2 Level 3 NAV (3) Total Common / collective trusts (3) : Blend funds $ — $ — $ — $ 90,338 $ 90,338 Mutual funds — — — 48,446 48,446 Corporate fixed income securities — 443,948 — — 443,948 Common stock 42,670 — — — 42,670 Government securities: U.S. government securities — 149,514 — — 149,514 Foreign government securities — 57,253 — — 57,253 Other fixed income securities — 21,107 — — 21,107 Other 1,107 35,721 — — 36,828 Total investments $ 43,777 $ 707,543 $ — $ 138,784 $ 890,104 The following table presents the fair value of the benefit plans' assets by asset category as of June 30, 2020: (in thousands) Level 1 Level 2 Level 3 NAV (3) Total Common / collective trusts (3) : Blend funds $ — $ — $ — $ 94,667 $ 94,667 Mutual funds — — — 59,674 59,674 Corporate fixed income securities — 394,521 — — 394,521 Common stock 38,487 — — — 38,487 Government securities: U.S. government securities — 178,364 — — 178,364 Foreign government securities — 61,153 — — 61,153 Other fixed income securities — 22,544 — — 22,544 Other 2,410 24,216 — — 26,626 Total investments $ 40,897 $ 680,798 $ — $ 154,341 $ 876,036 (3) Investments in common / collective trusts invest primarily in publicly traded securities and are valued using net asset value (NAV) of units of a bank collective trust. Therefore, these amounts have not been classified in the fair value hierarchy and are presented in the tables to reconcile the fair value hierarchy to the total fair value of plan assets. Defined Contribution Plans We sponsor several defined contribution retirement plans. Costs for defined contribution plans were $13.3 million, $14.7 million and $16.3 million in 2021, 2020 and 2019, respectively. Certain U.S. employees are eligible to participate in the Kennametal Thrift Plus Plan (Thrift), which is a qualified defined contribution plan under section 401(k) of the Internal Revenue Code. Under the Thrift, eligible employees receive a full match of their contributions up to 6 percent of eligible compensation. All contributions, including the company match and discretionary, are made in cash and invested in accordance with participants’ investment elections. There are no minimum amounts that must be invested in company stock, and there are no restrictions on transferring amounts out of company stock to another investment choice, other than excessive trading rules applicable to such investments. Employee contributions and our matching and discretionary contributions vest immediately as of the participants' employment dates.

Restructuring Charges [Abstract]
RESTRUCTURING AND RELATED CHARGES AND ASSET IMPAIRMENT CHARGES	RESTRUCTURING AND RELATED CHARGES FY20 Restructuring Actions In the June quarter of fiscal 2019, we implemented, and in fiscal 2020 substantially completed, the FY20 Restructuring Actions associated with our simplification/modernization initiative to reduce structural costs, improve operational efficiency and position us for long-term profitable growth. Total restructuring and related charges since inception of $54.8 million were recorded for this program through June 30, 2021, consisting of: $46.6 million in Metal Cutting and $8.3 million in Infrastructure. FY21 Restructuring Actions In the September quarter of fiscal 2020, we announced the initiation of restructuring actions in Germany associated with our simplification/modernization initiative to reduce structural costs. Subsequently, we also announced the acceleration of our other structural cost reduction plans including the closing of the Johnson City, Tennessee facility. Expected pre-tax charges for the FY21 Restructuring Actions are approximately $90 million. Total restructuring and related charges since inception of $82.2 million were recorded for this program through June 30, 2021, consisting of: $74.5 million in Metal Cutting and $7.7 million in Infrastructure. The majority of the remaining charges related to the FY21 Restructuring Actions are expected to be in the Metal Cutting segment. Annual Restructuring Charges During 2021, we recorded restructuring and related charges of $40.4 million, which consisted of $35.6 million in Metal Cutting and $4.8 million in Infrastructure. Of this amount, restructuring charges totaled $29.6 million, of which $0.5 million was related to inventory and was recorded in cost of goods sold. Restructuring-related charges of $10.8 million were recorded in cost of goods sold. During 2020, we recorded restructuring and related charges of $83.3 million. Of this amount, restructuring charges totaled $69.2 million, of which $0.9 million was related to inventory and was recorded in cost of goods sold. Restructuring-related charges of $14.1 million were recorded in cost of goods sold. During 2019, we recorded restructuring and related charges of $16.9 million, net of a $4.8 million gain on the sale of our previously closed Madison, AL manufacturing location as part of FY19 Restructuring Actions. Of this amount, restructuring charges totaled $19.5 million, of which $0.7 million was related to inventory and was recorded in cost of goods sold. Restructuring-related charges of $1.8 million were recorded in cost of goods sold and $0.3 million were recorded in operating expense during 2019. As of June 30, 2021, $19.9 million the restructuring accrual is recorded in other current liabilities and $9.9 million is recorded in other liabilities in our consolidated balance sheet. As of June 30, 2020, $34.9 million of the restructuring accrual is recorded in other current liabilities and $12.5 million is recorded in other liabilities in our consolidated balance sheet.

Financial Instruments, Owned, at Fair Value [Abstract]
Financial Instruments Disclosure [Text Block]	FINANCIAL INSTRUMENTS The methods used to estimate the fair value of our financial instruments are as follows: Cash and Equivalents, Revolving and Other Lines of Credit and Notes Payable The carrying amounts approximate their fair value because of the short maturity of the instruments. Long-Term Debt, Including Current Maturities Fixed rate debt had a fair market value of $644.2 million and $630.2 million at June 30, 2021 and 2020, respectively. The Level 2 fair value is determined based on the quoted market prices for similar debt instruments as of June 30, 2021 and 2020, respectively. Foreign Exchange Contracts All outstanding range forward contracts expired as of June 30, 2021. The notional amount of the contracts translated into U.S. dollars at June 30, 2020 was $2.2 million. We would have received an immaterial amount at June 30, 2020 to settle these contracts representing the fair value of these agreements. The carrying value equaled the fair value for these contracts at June 30, 2020. Fair value was estimated based on quoted market prices of comparable instruments. Interest Rate Swap Contracts During fiscal 2021, upon issuance of the Senior Unsecured Notes due 2031 (see Note 11 for more information) we settled the forward starting interest rate swap contracts used to hedge a portion of the interest rate risk related to the refinancing. The notional amount of the forward starting interest rate swap contracts at June 30, 2020 was $200.0 million. We recorded $2.1 million of liabilities as of June 30, 2020 related to these contracts. There were no interest rate swap contracts outstanding at June 30, 2021. Concentrations of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of temporary cash investments and trade receivables. By policy, we make temporary cash investments with high credit quality financial institutions and limit the amount of exposure to any one financial institution. With respect to trade receivables, concentrations of credit risk are significantly reduced because we serve numerous customers in many industries and geographic areas. We are exposed to counterparty credit risk for nonperformance of derivatives and, in the unlikely event of nonperformance, to market risk for changes in interest and currency exchange rates, as well as settlement risk. We manage exposure to counterparty credit risk through credit standards, diversification of counterparties and procedures to monitor concentrations of credit risk. We do not anticipate nonperformance by any of the counterparties. As of June 30, 2021 and 2020, we had no significant concentrations of credit risk.

All options were fully vested as of June 30, 2021 and June 30, 2020. Tax benefits relating to excess stock-based compensation deductions are presented in the consolidated statements of cash flows as operating cash inflows. Tax benefits resulting from stock-based compensation deductions were greater than the amounts reported for financial reporting purposes by $0.7 million in 2021, and less than amounts reported for financial reporting purposes by an immaterial amount in 2020 and by $1.3 million in 2019. The amount of cash received from the exercise of capital stock options during 2021, 2020 and 2019 was $6.6 million, $0.9 million and $4.8 million, respectively. The related tax benefit was $0.6 million in 2021, was immaterial in 2020, and was $0.5 million 2019. The total intrinsic value of options exercised in 2021, 2020 and 2019 was $2.4 million, $0.3 million and $2.4 million, respectively. Restricted Stock Units – Time Vesting and Performance Vesting Performance vesting restricted stock units are earned pro rata each year if certain performance goals are met over a three Changes in our time vesting and performance vesting restricted stock units for 2021 were as follows: Performance Performance Time Vesting Time Vesting Unvested, June 30, 2020 554,633 $ 34.26 1,039,695 $ 32.48 Granted 220,876 33.49 924,850 31.84 Vested (77,284) 47.47 (480,754) 33.88 Performance metric adjustments, net (100,000) 32.92 — — Other adjustments (4,565) 30.26 — — Forfeited (93,183) 32.39 (151,051) 30.87 Unvested, June 30, 2021 500,477 $ 32.53 1,332,740 $ 31.72 During 2021, 2020 and 2019, compensation expense related to time vesting and performance vesting restricted stock units was $23.9 million, $15.3 million and $21.9 million, respectively. Certain performance metrics related to fiscal 2020 were not met, resulting in an adjustment of 100,000 performance vesting stock units during 2021. As of June 30, 2021, the total unrecognized compensation cost related to unvested time vesting and performance vesting restricted stock units was $22.7 million and is expected to be recognized over a weighted average period of 1.8 years.

Environmental Remediation Obligations [Abstract]
ENVIRONMENTAL MATTERS	ENVIRONMENTAL MATTERS The operation of our business has exposed us to certain liabilities and compliance costs related to environmental matters. We are involved in various environmental cleanup and remediation activities at certain sites associated with our current or former operations. We establish and maintain accruals for certain potential environmental obligations. At June 30, 2021 and 2020, the balances of these liabilities were $14.7 million, of which $2.6 million was current, and $15.6 million, of which $6.1 million was current, respectively. These accruals represent anticipated costs associated with the remediation of these issues and are generally not discounted. The accruals we have established for environmental liabilities represent our best current estimate of the probable and reasonably estimable costs of addressing identified environmental situations, based on our review of currently available evidence, and taking into consideration our prior experience in remediation and that of other companies, as well as public information released by the United States Environmental Protection Agency (USEPA), other governmental agencies and by the Potentially Responsible Party (PRP) groups in which we are participating. Although the accruals currently appear to be sufficient to cover these environmental obligations, there are uncertainties associated with environmental liabilities, and we can give no assurance that our estimate of any environmental liability will not increase or decrease in the future. The recorded and unrecorded liabilities for all environmental concerns could change substantially due to factors such as the nature and extent of contamination, changes in remedial requirements, technological changes, discovery of new information, the financial strength of other PRPs, the identification of new PRPs and the involvement of and direction taken by the government on these matters. Among other environmental laws, we are subject to the Comprehensive Environmental Response Compensation and Liability Act of 1980, under which we have been identified by the USEPA or other third party as a PRP with respect to environmental remedial costs at certain sites. We have evaluated our claims and potential liability associated with these sites based upon the best information currently available to us. We believe our environmental accruals will be adequate to cover our portion of the environmental remedial costs at those sites where we have been designated a PRP, to the extent these expenses are probable and reasonably estimable.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENCIES Legal Matters Various lawsuits arising during the normal course of business are pending against us. In our opinion, the ultimate liability, if any, resulting from these matters will have no significant effect on our consolidated financial position or results of operations. Lease Commitments We lease a wide variety of facilities and equipment under operating leases, primarily for warehouses, production and office facilities and equipment. Refer to Note 9 for more information. Purchase Commitments We have purchase commitments for materials, supplies and machinery and equipment as part of the ordinary conduct of business. Some of these commitments extend beyond one year and are based on minimum purchase requirements. We believe these commitments are not at prices in excess of current market. Other Contractual Obligations We do not have material financial guarantees or other contractual commitments that are reasonably likely to adversely affect our liquidity.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jun. 30, 2021
Accounting Policies [Abstract]
Principles of Consolidation	PRINCIPLES OF CONSOLIDATION The consolidated financial statements include our accounts and those of our subsidiaries in which we have a controlling interest. All significant intercompany balances and transactions are eliminated.
Use of Estimates in the Preparation of Financial Statements	USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS In preparing our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP), we make judgments and estimates about the amounts reflected in our consolidated financial statements. As part of our financial reporting process, our management collaborates to determine the necessary information on which to base our judgments and develop estimates used to prepare the consolidated financial statements. We use historical experience and available information to make these judgments and estimates. However, different amounts could be reported using different assumptions and in light of different facts and circumstances. Therefore, actual amounts could differ from the estimates reflected in our consolidated financial statements.
Cash and Cash Equivalents	CASH AND CASH EQUIVALENTS Cash investments having original maturities of three months or less are considered cash equivalents. Cash equivalents principally consist of investments in money market funds and bank deposits at June 30, 2021.
Accounts Receivable	ACCOUNTS RECEIVABLE We market our products to a diverse customer base throughout the world. Trade credit is extended based upon periodically updated evaluations of each customer’s ability to satisfy its obligations. We make judgments as to our ability to collect outstanding receivables and provide allowances for the portion of receivables when collection becomes doubtful. Accounts receivable reserves are determined based upon an aging of accounts and a review of specific accounts.
Inventory	INVENTORIES We use the last-in, first-out (LIFO) method for determining the cost of a significant portion of our United States (U.S.) inventories, and they are stated at the lower of cost or market. The cost of the remainder of our inventories is measured using approximate costs determined on the first-in, first-out basis or using the average cost method, and are stated at the lower of cost or net realizable value. When market conditions indicate an excess of carrying costs over market value, a lower of cost or net realizable value provision or a lower of cost or market provision, as applicable, is recorded. Once inventory is determined to be excess or obsolete, a new cost basis is established that is not subsequently written back up in future periods.
Property, Plant and Equipment	PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are carried at cost. Major improvements are capitalized, while maintenance and repairs are expensed as incurred. Retirements and disposals are removed from cost and accumulated depreciation accounts, with the gain or loss reflected in operating income. Interest related to the construction of major facilities is capitalized as part of the construction costs and is depreciated over the facilities' estimated useful lives. Depreciation for financial reporting purposes is computed using the straight-line method over the following estimated useful lives: building and improvements over 15-40 years; machinery and equipment over 4-15 years; furniture and fixtures over 5-10 years and computer hardware and software over 3-5 years.
Long Lived Assets	LONG-LIVED ASSETS We evaluate the recoverability of property, plant and equipment, operating lease right-of-use (ROU) assets and intangible assets that are amortized, whenever events or changes in circumstances indicate the carrying amount of any such assets may not be fully recoverable. Changes in circumstances include technological advances, changes in our business model, capital structure, economic conditions or operating performance. Our evaluation is performed at the asset group level, based upon, among other things, our assumptions about the estimated future undiscounted cash flows these assets are expected to generate. When the sum of the undiscounted cash flows is less than the carrying value, we will recognize an impairment loss to the extent that carrying value exceeds fair value. We apply our best judgment when performing these evaluations to determine if a triggering event has occurred, the undiscounted cash flows used to assess recoverability and the fair value of the asset group.
Goodwill and Other Intangible Assets	GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill represents the excess of cost over the fair value of the net assets of acquired companies. Goodwill and other intangible assets with indefinite lives are tested at least annually for impairment. We perform our annual impairment tests during the June quarter in connection with our annual planning process unless there are impairment indicators based on the results of an ongoing cumulative qualitative assessment that warrant a test prior to that quarter. We evaluate the recoverability of goodwill for each of our reporting units by comparing the fair value of each reporting unit with its carrying value. The fair values of our reporting units are determined using a combination of a discounted cash flow analysis and market multiples based upon historical and projected financial information. We apply our best judgment when assessing the reasonableness of the financial projections used to determine the fair value of each reporting unit. We evaluate the recoverability of indefinite-lived intangible assets using a discounted cash flow analysis based on projected financial information. This evaluation is sensitive to changes in market interest rates and other external factors. The majority of our intangible assets with definite lives are amortized on a straight-line basis, while certain customer-related intangible assets are amortized on an accelerated method. Identifiable assets with finite lives are reviewed for impairment when events or circumstances indicate that the carrying value may not be recoverable.
Pension and Other Postretirement Benefits	PENSION AND OTHER POSTRETIREMENT BENEFITS We sponsor these types of benefit plans for certain employees and retirees. Accounting for the cost of these plans requires the estimation of the cost of the benefits to be provided well into the future and attributing that cost over either the expected work life of employees or over average life of participants participating in these plans, depending on plan status and on participant population. This estimation requires our judgment about the discount rate used to determine these obligations, expected return on plan assets, rate of future compensation increases, rate of future health care costs, withdrawal and mortality rates and participant retirement age. Differences between our estimates and actual results may significantly affect the cost of our obligations under these plans. In the valuation of our pension and other postretirement benefit liabilities, management utilizes various assumptions. Discount rates are derived by identifying a theoretical settlement portfolio of high quality corporate bonds sufficient to provide for a plan’s projected benefit payments. This rate can fluctuate based on changes in the corporate bond yields. The long-term rate of return on plan assets is estimated based on an evaluation of historical returns for each asset category held by the plans, coupled with the current and short-term mix of the investment portfolio. The historical returns are adjusted for expected future market and economic changes. This return will fluctuate based on actual market returns and other economic factors. The rate of future health care costs is based on historical claims and enrollment information projected over the next year and adjusted for administrative charges. This rate is expected to decrease until 2027. Future compensation rates, withdrawal rates and participant retirement age are determined based on historical information. These assumptions are not expected to significantly change. Mortality rates are determined based on a review of published mortality tables.
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share is computed using the weighted average number of shares outstanding during the period, while diluted earnings per share is calculated to reflect the potential dilution that would occur related to the issuance of capital stock under stock option grants, performance awards and restricted stock units. The difference between basic and diluted earnings per share relates solely to the effect of capital stock options, performance awards and restricted stock units. The following tables provide the computation of diluted shares outstanding: (in thousands) 2021 2019 Weighted-average shares outstanding during period 83,602 82,379 Add: Unexercised stock options and unvested restricted stock units 731 912 Number of shares on which diluted earnings per share is calculated 84,333 83,291 Unexercised stock options with an exercise price greater than the average market price and restricted stock units not included in the computation because they were anti-dilutive 295 427
Revenue Recognition	REVENUE RECOGNITION The Company's contracts with customers are comprised of purchase orders, and for larger customers, may also include long-term agreements. We account for a contract when it has approval and commitment from both parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable. These contracts with customers typically relate to the manufacturing of products, which represent single performance obligations that are satisfied when control of the product passes to the customer. The Company considers the timing of right to payment, transfer of risk and rewards, transfer of title, transfer of physical possession and customer acceptance when determining when control transfers to the customer. As a result, revenue is generally recognized at a point in time - either upon shipment or delivery - based on the specific shipping terms in the contract. The shipping terms vary across all businesses and depend on the product, customary local commercial terms and the type of transportation. Shipping and handling activities are accounted for as activities to fulfill a promise to transfer a product to a customer and as such, costs incurred are recorded when the related revenue is recognized. Payment for products is due within a limited time period after shipment or delivery, typically within 30 to 90 calendar days of the respective invoice dates. The Company does not generally offer extended payment terms. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. Amounts billed and due from our customers are classified as accounts receivable, less allowance for doubtful accounts on the consolidated balance sheets. Certain contracts with customers, primarily distributor customers, have an element of variable consideration that is estimated when revenue is recognized under the contract. Variable consideration primarily includes volume incentive rebates, which are based on achieving a certain level of purchases and other performance criteria as established by our distributor programs. These rebates are estimated based on projected sales to the customer and accrued as a reduction of net sales as they are earned. The majority of our products are consumed by our customers or end users in the manufacture of their products. Historically, we have experienced very low levels of returned products and do not consider the effect of returned products to be material. We have recorded an estimated returned goods allowance to provide for any potential returns. We warrant that products sold are free from defects in material and workmanship under normal use and service when correctly installed, used and maintained. This warranty terminates 30 days after delivery of the product to the customer and does not apply to products that have been subjected to misuse, abuse, neglect or improper storage, handling or maintenance. Products may be returned to Kennametal only after inspection and approval by Kennametal and upon receipt by the customer of shipping instructions from Kennametal. We have included an estimated allowance for warranty returns in our returned goods allowance discussed above. See "Note 21. Segment Data" for disaggregation of revenue by geography and end market. The Company records a contract asset when it has a right to payment from a customer that is conditioned on events that have occurred other than the passage of time. The Company also records a contract liability when customers prepay but the Company has not yet satisfied its performance obligation. The Company did not have any material remaining performance obligations, contract assets or liabilities as of June 30, 2021 and 2020. The Company pays sales commissions related to certain contracts, which qualify as incremental costs of obtaining a contract. However, the Company applies the practical expedient that allows an entity to recognize incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that would have been recognized is one year or less. These costs are recorded within operating expense in our consolidated statements of income. SHIPPING AND HANDLING FEES AND COSTS All fees billed to customers for shipping and handling are classified as a component of sales. All costs associated with shipping and handling are classified as a component of cost of goods sold.
Stock-Based Compensation	STOCK-BASED COMPENSATION We recognize stock-based compensation expense for all stock options, restricted stock awards and restricted stock units over the period from the date of grant to the date when the award is no longer contingent on the employee providing additional service (substantive vesting period), net of expected forfeitures. We utilize the Black-Scholes valuation method to establish the fair value of all stock option awards. Time vesting stock units are valued at the market value of the stock on the grant date. Performance vesting stock units with a market condition are valued using a Monte Carlo model.
Research and Development Costs	RESEARCH AND DEVELOPMENT COSTS Research and development costs of $39.5 million, $38.7 million and $39.0 million in 2021, 2020 and 2019, respectively, were expensed as incurred. These costs are included in operating expense in the consolidated statements of income.
Income Taxes	INCOME TAXES Deferred income taxes are recognized based on the future income tax effects (using enacted tax laws and rates) of differences in the carrying amounts of assets and liabilities for financial reporting and tax purposes. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not (greater than 50 percent) that a tax benefit will not be realized. In evaluating the need for a valuation allowance, we consider all potential sources of taxable income, including income available in carryback periods, future reversals of taxable temporary differences, projections of taxable income, and income from tax planning strategies, as well as all available positive and negative evidence. Positive evidence includes factors such as a history of profitable operations, and projections of future profitability within the carry forward period, including taxable income from tax planning strategies. Negative evidence includes items such as cumulative losses, projections of future losses, or carryforward periods that are not long enough to allow for the utilization of the deferred tax asset based on existing projections of income. Upon changes in facts and circumstances, we may conclude that deferred tax assets for which no valuation allowance is currently recorded may not be realized, resulting in a charge to establish a valuation allowance. Existing valuation allowances are re-examined under the same standards of positive and negative evidence. If it is determined that it is more likely than not that a deferred tax asset will be realized, the appropriate amount of the valuation allowance, if any, is released.
Derivative Instruments and Hedging Activities	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES As part of our financial risk management program, we use certain derivative financial instruments. We do not enter into derivative transactions for speculative purposes and, therefore, hold no derivative instruments for trading purposes. We use derivative financial instruments to provide predictability to the effects of changes in foreign exchange rates on our consolidated results. Our objective in managing foreign exchange exposures with derivative instruments is to reduce volatility in cash flow, allowing us to focus more of our attention on business operations. With respect to interest rate management, we use forward-starting interest rate swaps to effectively hedge the variability in future benchmark interest payments attributable to changes in interest rates on forecasted issuances of fixed-rate debt.
Cash Flow Hedges	CASH FLOW HEDGES Currency Forward contracts and range forward contracts (a transaction where both a put option is purchased and a call option is sold) are designated as cash flow hedges and hedge anticipated cash flows from cross-border intercompany sales of products and services. Gains and losses realized on these contracts are recorded in accumulated other comprehensive loss, and are recognized as a component of other income, net when the underlying sale of products or services is recognized into earnings. Interest Rate Forward starting interest rate swap contracts are designated as cash flow hedges and hedge a portion of the interest rate risk related to anticipated issuances of debt. Gains and losses realized on these contracts are recorded in accumulated other comprehensive loss, and are recognized as a component of interest expense when the interest payments on the future debt interest are recognized into earnings.
Net Investment Hedges [Policy Text Block]	NET INVESTMENT HEDGES We designate financial instruments as net investment hedges from time to time to hedge the foreign exchange exposure of our net investment in foreign currency-based subsidiaries. The remeasurements of these non-derivatives designated as net investment hedges are calculated each period with changes reported in foreign currency translation adjustment within accumulated other comprehensive loss. Such amounts will remain in accumulated other comprehensive loss unless we complete or substantially complete liquidation or disposal of our investment in the underlying foreign operations.
Currency Translation	CURRENCY TRANSLATION Assets and liabilities of international operations are translated into U.S. dollars using year-end exchange rates, while revenues and expenses are translated at average exchange rates throughout the year. The resulting net translation adjustments are recorded as a component of accumulated other comprehensive loss. The local currency is the functional currency of most of our locations. Losses of $3.3 million, $3.4 million and $2.7 million from currency transactions were included in other income, net in 2021, 2020 and 2019, respectively.
New Accounting Standards	NEW ACCOUNTING STANDARDS Effective July 1, 2020, the Company adopted Accounting Standards Update (ASU) No. 2016-13, Financial Instruments – Credit Losses. This ASU added a new impairment model (known as the current expected credit loss (CECL) model) that is based on expected losses rather than incurred losses. The new guidance applies to all financial assets, including trade receivables. The Company adopted the ASU on a modified retrospective approach. Under this method of adoption, there was no cumulative-effect adjustment to beginning retained earnings on the consolidated balance sheets. Adoption of this standard did not have a material effect on the Company's consolidated financial statements.
