Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION
	The condensed consolidated financial statements, which include our accounts and those of our majority-owned subsidiaries, should be read in conjunction with our 2014 Annual Report on Form 10-K. The condensed consolidated balance sheet as of June 30, 2014 was derived from the audited balance sheet included in our 2014 Annual Report on Form 10-K. These interim statements are unaudited; however, we believe that all adjustments necessary for a fair statement of the results of the interim periods were made and all adjustments are normal adjustments. The results for the six months ended December 31, 2014 and 2013 are not necessarily indicative of the results to be expected for a full fiscal year. Unless otherwise specified, any reference to a “year” is to a fiscal year ended June 30. For example, a reference to 2015 is to the fiscal year ending June 30, 2015. When used in this Form 10-Q, unless the context requires otherwise, the terms “we,” “our” and “us” refer to Kennametal Inc. and its subsidiaries.
	During the current quarter, the Company revised its condensed consolidated statement of cash flow for the three months ended September 30, 2014 to correctly present the net cash flow provided by operating activities and effect of exchange rate changes on cash and cash equivalents, resulting in an increase of $8.4 million to operating cash flows and a corresponding decrease in effect of exchange rate changes on cash and cash equivalents. The Company has evaluated this error and determined that the impact of the error was not material to the previously issued interim and annual financial statements.

NEW ACCOUNTING STANDARDS	NEW ACCOUNTING STANDARDS
	Adopted
	In July 2013, the Financial Accounting Standards Board (FASB) issued new guidance on the presentation in the financial statements of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The guidance takes into account these losses and carryforwards as well as the intended or likelihood of use of the unrecognized tax benefit in determining the balance sheet classification as an asset or liability. This guidance was effective for Kennametal beginning July 1, 2014 and did not have a material impact.

Business Combinations [Abstract]
ACQUISITION	ACQUISITION
	On November 4, 2013, the Company completed its transaction to acquire the Tungsten Materials Business (TMB) from Allegheny Technologies Incorporated (ATI) which included all of the assets of TDY Industries, LLC, a wholly owned subsidiary of ATI, used or held for use by TDY in connection with the business; and all of the shares of TDY Limited and ATI Holdings SAS, both wholly-owned subsidiaries of ATI, for a purchase price of $607.0 million, net of cash acquired. We funded the acquisition primarily through a combination of cash from operations and available borrowings under our existing credit facility.
	The accompanying condensed consolidated balance sheet as of December 31, 2014 reflects the final allocation of the purchase price. No material adjustments have been made to the allocation in conjunction with finalization.
	The accompanying condensed consolidated statement of income for the six months ended December 31, 2014, includes net sales of $123.3 million and net income of $6.1 million related to TMB.
	Unaudited Pro Forma Financial Information
	The following unaudited pro forma summary of operating results presents the consolidated results of operations as if the TMB acquisition had occurred on July 1, 2012. These amounts were calculated after applying our accounting policies and adjusting TMB’s results to reflect increased depreciation and amortization expense resulting from recording fixed assets and intangible assets at fair value, as well as increased cost of sales resulting from recording inventory at fair value. The pro forma results have been presented for comparative purposes only, include no expected sales or cost synergies and are not indicative of future results of operations or what would have occurred had the acquisition been made on July 1, 2012.
	Unaudited pro forma summary of operating results of Kennametal, assuming the acquisition had occurred as of July 1, 2012, are as follows:

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 December 31, 2014, 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)	$	—	$	9,762	$	—	$	9,762

	Total liabilities at fair value	$	—	$	1,053	$	14,000	$	15,053
	(1) Currency derivatives are valued based on observable market spot and forward rates and are classified within Level 2 of the fair value hierarchy.
	The fair value of contingent consideration payable that was classified as Level 3 relates to our probability assessments of expected future milestone targets, primarily associated with product delivery, related to the Emura acquisition. The contingent consideration is to be paid over the next 2 years. During the three months ended December 31, 2014, the Company paid $4.0 million in conjunction with achieved milestone targets. The Company reassessed this contingent consideration and determined that no adjustment to the fair value of the remaining contingent consideration was necessary and that no changes in the expected outcome have occurred during the quarter ended December 31, 2014.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
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 account for derivative instruments as a hedge of the related asset, liability, firm commitment or anticipated transaction, when the derivative is specifically designated and qualifies as a hedge of such items. Our objective in managing foreign exchange exposures with derivative instruments is to reduce volatility in cash flow. We measure hedge effectiveness by assessing the changes in the fair value or expected future cash flows of the hedged item. The ineffective portions are recorded in other expense, net.
	The fair value of derivatives designated and not designated as hedging instruments in the condensed consolidated balance sheet are as follows:
	(in thousands)	December 31,			June 30,
		2014			2014
	Derivatives designated as hedging instruments
	Other current assets - range forward contracts	$	3,668		$	184
	Other current liabilities - range forward contracts	—			(6		)
	Other assets - range forward contracts	—			42
	Total derivatives designated as hedging instruments	3,668			220
	Derivatives not designated as hedging instruments
	Other current assets - currency forward contracts	6,094			27
	Other current liabilities - currency forward contracts	(120		)	(1,047		)
	Total derivatives not designated as hedging instruments	5,974			(1,020		)
	Total derivatives	$	9,642		$	(800	)
	Certain currency forward contracts that hedge significant cross-border intercompany loans are considered as other derivatives and therefore do not qualify for hedge accounting. These contracts are recorded at fair value in the condensed consolidated balance sheet, with the offset to other expense, net. (Gains) losses related to derivatives not designated as hedging instruments have been recognized as follows:
		Three Months Ended December 31,						Six Months Ended December 31,
	(in thousands)	2014			2013			2014			2013
	Other (income) expense, net - currency forward contracts	$	(2,273	)	$	72		$	(7,169	)	$	114
	CASH FLOW HEDGES
	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 at maturity are recorded in accumulated other comprehensive loss and are recognized as a component of other expense (income), net when the underlying sale of products or services is recognized into earnings. The notional amount of the contracts translated into U.S. dollars at December 31, 2014 and June 30, 2014, was $57.0 million and $91.1 million, respectively. The time value component of the fair value of range forward contracts is excluded from the assessment of hedge effectiveness. Assuming the market rates remain constant with the rates at December 31, 2014, we expect to recognize into earnings in the next 12 months $2.3 million of income on outstanding derivatives.
	In February 2012, we settled forward starting interest rate swap contracts to convert $150.0 million of our floating rate debt to fixed rate debt. Upon settlement, we made a cash payment of $22.4 million. The loss is being amortized as a component of interest expense over the term of the related debt using the effective interest rate method. During the three months ended December 31, 2014 and 2013, $0.5 million and $0.5 million was recognized as interest expense, respectively. During the six months ended December 31, 2014 and 2013, $1.0 million and $1.0 million was recognized as interest expense, respectively.
	The following represents gains and losses related to cash flow hedges:
		Three Months Ended December 31,						Six Months Ended December 31,
	(in thousands)	2014			2013			2014			2013
	Gains (losses) recognized in other comprehensive income, net	$	1,205		$	(273	)	$	2,712		$	(843	)
	Losses reclassified from accumulated other comprehensive loss into other expense (income), net	$	152		$	324		$	502		$	714
	No portion of the gains or losses recognized in earnings was due to ineffectiveness and no amounts were excluded from our effectiveness testing for the six months ended December 31, 2014 and 2013.

	Restructuring and Related
	As previously set forth in the 2014 Annual Report on Form 10-K, we are implementing restructuring actions in conjunction with our Phase 1 restructuring program to achieve synergies across Kennametal as a result of the TMB acquisition by consolidating operations among both organizations, reducing administrative overhead and leveraging the supply chain. These restructuring actions are expected to be completed by the end of fiscal 2016 and are anticipated to be mostly cash expenditures.
	During the six months ended December 31, 2014, we recognized restructuring and related charges of $20.4 million, of this amount, restructuring charges totaled $8.6 million, of which $0.2 million were charges related to inventory disposals and were recorded in cost of goods sold. Restructuring-related charges of $6.3 million were recorded in cost of goods sold and $5.5 million in operating expense for the six months ended December 31, 2014.
	During the six months ended December 31, 2013, we recorded restructuring charges of $2.3 million.
	The total pre-tax charges for Phase 1 programs are expected to be in the range of $55 million to $60 million, which is expected to be approximately 50 percent Industrial and 50 percent Infrastructure. Total restructuring and related charges since inception of $39.5 million have been recorded for these programs through December 31, 2014: $24.5 million in Industrial, $13.1 million in Infrastructure, and $1.8 million in Corporate.
	The restructuring accrual is recorded in other current liabilities in our condensed consolidated balance sheet and the amount attributable to each segment is as follows:

	We used the last-in, first-out (LIFO) method of valuing inventories for 47 percent and 43 percent of total inventories at December 31, 2014 and June 30, 2014, respectively. Since inventory valuations under the LIFO method are based on an annual determination of quantities and costs as of June 30 of each year, the interim LIFO valuations are based on our projections of expected year-end inventory levels and costs. Therefore, the interim financial results are subject to any final year-end LIFO inventory adjustments.
	Inventories consisted of the following:

	Our $600 million five-year, multi-currency, revolving credit facility (2011 Credit Agreement) requires us to comply with various restrictive and affirmative covenants, including two financial covenants: a maximum leverage ratio and a minimum consolidated interest coverage ratio (as those terms are defined in the agreement). We were in compliance with all covenants as of December 31, 2014. We had $174.1 million and $287.1 million of borrowings outstanding under the 2011 Credit Agreement as of December 31, 2014 and June 30, 2014, respectively. Borrowings under the 2011 Credit Agreement are guaranteed by our significant domestic subsidiaries. The 2011 Credit Agreement matures in April 2018.
	Fixed rate debt had a fair market value of $703.3 million and $705.3 million at December 31, 2014 and June 30, 2014, respectively. The Level 2 fair value is determined based on the quoted market price of this debt as of December 31, 2014 and June 30, 2014, respectively.

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 of our locations.
	Superfund Sites We are involved as a potentially responsible party (PRP) at various sites designated by the United States Environmental Protection Agency (USEPA) as Superfund sites. For certain of these sites, we have evaluated the claims and potential liabilities and have determined that neither are material, individually or in the aggregate. For certain other sites, proceedings are in the very early stages and have not yet progressed to a point where it is possible to estimate the ultimate cost of remediation, the timing and extent of remedial action that may be required by governmental authorities or the amount of our liability alone or in relation to that of any other PRP.
	Other Environmental Matters We establish and maintain reserves for other potential environmental issues. At December 31, 2014 and June 30, 2014, the balances of these reserves were $12.6 million and $11.0 million. These reserves represent anticipated costs associated with the remediation of these issues.
	The reserves we have established for environmental liabilities represent our best current estimate of the costs of addressing all 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 USEPA, other governmental agencies and by the PRP groups in which we are participating. Although the reserves currently appear to be sufficient to cover these environmental liabilities, 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 reserved and unreserved 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.
	We maintain a Corporate Environmental Health and Safety (EHS) Department to monitor compliance with environmental regulations and to oversee remediation activities. In addition, we have designated EHS coordinators who are responsible for each of our global manufacturing facilities. Our financial management team periodically meets with members of the Corporate EHS Department and the Corporate Legal Department to review and evaluate the status of environmental projects and contingencies. On a quarterly basis, we review financial provisions and reserves for environmental contingencies and adjust these reserves when appropriate.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES
	The effective income tax rate for the three months ended December 31, 2014 and 2013 was negative 12.7 percent (provision on a loss) and 40.8 percent (provision on income), respectively. The effective income tax rate for six months ended December 31, 2014 and 2013 was negative 20.1 percent (provision on a loss) and 31.8 percent (provision on income), respectively. The change in both periods was primarily driven by the asset impairment charges recorded in the current quarter, most of which could not be tax effected, lower relative U.S. current year earnings compared with the rest of the world where the tax rates are generally lower, and favorable effects of the extension of the credit for increase in research activities contained in the Tax Increase Prevention Act of 2014 that was enacted during the current quarter. The prior year rate included a tax charge related to a change in assertion of a foreign subsidiary’s certain undistributed earnings, which were no longer considered permanently reinvested.

Earnings_Per_Share

Earnings Per Share	6 Months Ended

Earnings Per Share [Abstract]
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 occurs related to the issuance of capital stock under stock option grants and restricted stock units. The difference between basic and diluted earnings per share relates solely to the effect of capital stock options and restricted stock units.
	For the three and six months ended December 31, 2014, the effect of unexercised capital stock options and unvested restricted stock units was anti-dilutive as a result of a net loss in the periods and therefore has been excluded from diluted shares outstanding as well as from the diluted earnings per share calculation. For purposes of determining the number of diluted shares outstanding for the three and six months ended December 31, 2013, weighted average shares outstanding for basic earnings per share calculations were increased due solely to the dilutive effect of unexercised capital stock options and unvested restricted stock units by $1.0 million and 1.0 million shares, respectively. Unexercised capital stock options and restricted stock units of 0.2 million shares and 0.3 million shares for the three and six months ended December 31, 2013, respectively, were not included in the computation of diluted earnings per share because the option exercise price was greater than the average market price, and therefore the inclusion would have been anti-dilutive.

Goodwill and Intangible Assets Disclosure [Abstract]
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. We also perform specific impairment tests on an interim basis based on the results of an ongoing cumulative qualitative assessment if indicative of impairment of the goodwill for a reporting unit or an indefinite-lived intangible asset. 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.
	Late in the December quarter, the Company experienced an abrupt change in customer demand in the oil and gas markets that is expected to continue into the foreseeable future, coupled with the severe and persistent decline in the earthworks markets. In view of the severe downturn in the global Infrastructure markets in the December quarter, we made an assessment of the possible impairment of the goodwill and other long-lived assets of our Infrastructure reporting unit. As a result of this assessment, we determined that the magnitude and duration of the economic downturn of the Infrastructure end markets, as well as other factors, necessitated an interim impairment test of our Infrastructure reporting unit. As a result of our test, we recorded a preliminary non-cash pre-tax impairment charge of $376.5 million in the Infrastructure segment, of which $375.0 million was for goodwill and $1.5 million was for an indefinite-lived trademark intangible asset. The goodwill impairment charge is subject to finalization of fair values related to intangibles and property, plant and equipment, which we expect to complete in the third quarter of fiscal 2015. Goodwill of $266.2 million remains on the books of our Infrastructure segment.
	Identifiable assets with finite lives are reviewed for impairment whenever events or circumstances indicate that the carrying value may not be recoverable. During the December quarter, we performed a preliminary review of our identifiable assets with finite lives and preliminarily determined that the assets were not impaired. The review is subject to finalization, which we expect to complete in the third quarter of fiscal 2015.
	The further acceleration or extended persistence of the current downturn in the global end markets could have a further negative impact on our business and financial performance. We are currently in the beginning stages of exploring strategic alternatives for several businesses within the Infrastructure segment, which have total estimated net book values of approximately $150 million to $200 million as of December 31, 2014. As the strategic direction has not yet been determined for these businesses, the Company cannot determine if additional impairment charges are either probable or estimable.
	A summary of the carrying amount of goodwill attributable to each segment, as well as the changes in such, is as follows:
	(in thousands)	Industrial				Infrastructure				Total
	Gross goodwill	$	472,337			$	654,081			$	1,126,418

	During the three months ended December 31, 2014, an impairment of $10.5 million was recorded for a contract-based technology intangible asset that was part of the Infrastructure segment, resulting in a non-cash impairment charge of $5.5 million and a reduction in a liability of $5.0 million. As previously mentioned, we recorded a $1.5 million impairment for an indefinite-lived trademark intangible asset as a result of our interim impairment test of our Infrastructure segment.
	During the six months ended December 31, 2014, we recorded amortization expense of $14.0 million related to our other intangible assets and unfavorable currency translation adjustments of $7.1 million.
