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 2013 Annual Report on Form 10-K. The condensed consolidated balance sheet as of June 30, 2013 was derived from the audited balance sheet included in our 2013 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 nine months ended March 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 2014 is to the fiscal year ending June 30, 2014. When used in this Quarterly Report on Form 10-Q, unless the context requires otherwise, the terms “we,” “our” and “us” refer to Kennametal Inc. and its subsidiaries.

	NEW ACCOUNTING STANDARDS
	Adopted
	As of July 1, 2013, Kennametal adopted disclosure requirements related to reclassifications out of accumulated other comprehensive income by component. See Note 17 to these condensed consolidated financial statements for required disclosures. Other than the change in disclosures, the adoption of this guidance had no impact on the condensed consolidated financial statements.
	As of July 1, 2013, Kennametal adopted additional guidance on testing indefinite lived intangible assets for impairment. The guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of an indefinite lived intangible asset is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step impairment test. The adoption of this guidance had no impact on the condensed consolidated financial statements.

Business Combinations [Abstract]	'
ACQUISITION	'
	ACQUISITIONS
	TMB
	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.
	TMB, with approximately $340.0 million in annual sales in calendar 2012, is a leading producer of tungsten metallurgical powders, as well as tooling technologies and components. The business has approximately 1,175 employees in 12 locations across 7 countries. The acquisition aligns with the Company's long-term growth strategies, expands presence in aerospace and energy end markets, further augments the Company's tooling portfolio and accelerates our metallurgical strategy including planned tungsten carbide recycling and production.
	As part of the acquisition of TMB, Kennametal incurred $2.4 million and $5.3 million for the three and nine months ended March 31, 2014 of acquisition-related costs, which are included in operating expense.
	Purchase Price Allocation
	In accordance with the accounting guidance for business combinations, the TMB acquisition was accounted for under the acquisition method of accounting and accordingly, the purchase price has been allocated to the assets acquired and liabilities assumed based on estimated fair values at the date of acquisition. The condensed consolidated balance sheet as of March 31, 2014 reflects the preliminary allocation of the purchase price and is subject to revision when appraisals are finalized, which is expected to be in the fourth quarter of fiscal 2014.
	The preliminary allocation of the purchase price to the fair values of the assets acquired and liabilities assumed is as follows:
	(in thousands)	Total
	ASSETS
	Current assets:
	Cash and cash equivalents	$	1,294
	Accounts Receivable	41,164
	Inventory	98,664
	Other current assets	4,014
	Total current assets	$	145,136
	Property and equipment	129,752
	Goodwill	240,948
	Other intangible assets	125,305
	Deferred income taxes	6,419
	Other	603
	Total assets	$	648,163
	LIABILITIES
	Current liabilities:
	Accounts payable	$	21,001
	Accrued payroll	3,646
	Accrued expenses	3,159
	Total current liabilities	$	27,806
	Deferred income taxes	4,145
	Other long-term liabilities	7,982
	Total liabilities	39,933
	Net assets acquired	$	608,230
	In connection with this acquisition, we identified and valued certain intangible assets, including existing customer relationships, technologies and trademarks, as further discussed in Note 18. It is expected that the majority of the preliminary goodwill recorded of $240.9 million will be deductible for tax purposes. The goodwill is attributable to the operating synergies we expect to gain from the acquisition. These intangible assets are part of both the Industrial and Infrastructure segments.
	TMB contributed net sales of $77.7 million and net loss of $4.4 million during the three months ended March 31, 2014. TMB contributed net sales of $122.5 million and net loss of $11.5 million during the five months ended March 31, 2014.
	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 amortization resulting from recording inventory at fair value. The pro forma results for the three and nine months ended March 31, 2014 exclude $2.5 million and $4.4 million of acquisition-related and restructuring-related pre-tax costs, respectively. The pro forma results for the three and nine months ended March 31, 2013 includes $7.7 million and $8.4 million, respectively, of integration-related pre-tax costs. 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:

	Emura
	On August 1, 2013, the Company acquired the operating assets of Comercializadora Emura S.R.L. and certain related entities (Emura), based in La Paz, Bolivia, and secured related material sourcing agreements for a purchase price of $40.1 million, of which $26.1 million represents cash paid, of which $25.6 million was paid in fiscal year 2014 and $0.5 million was paid in fiscal year 2013, and $14.0 million of contingent consideration (see Note 6). Emura's principal operations is engaged in collecting, testing, processing and exporting tungsten ore material, and was a long-standing supplier to Kennametal. The addition of Emura enhances the Company's strategic tungsten sourcing capabilities to serve growth globally.

	On September 30, 2013, the Company completed one other acquisition in the Infrastructure segment for $2.0 million.

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 March 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)	$	—	$	300	$	—	$	300
	Total assets at fair value	$	—	$	300	$	—	$	300

	Contingent consideration	—		—		14,000		14,000
	Total liabilities at fair value	$	—	$	457	$	14,000	$	14,457
	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 3 years. During the current quarter the Company reassessed this contingent consideration and determined that no adjustment to the fair value was deemed necessary and that no changes in the expected outcome have occurred during the quarter ended March 31, 2014.
	As of June 30, 2013, 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:

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(income) 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)	March 31,			June 30,
		2014			2013
	Derivatives designated as hedging instruments
	Other current assets - range forward contracts	$	129		$	658

	Other current liabilities - currency forward contracts	(22		)	(8		)
	Total derivatives not designated as hedging instruments	103			40
	Total derivatives	$	(157	)	$	245
	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 (income) expense, net. (Gains) losses related to derivatives not designated as hedging instruments have been recognized as follows:
		Three Months Ended March 31,						Nine Months Ended

	FAIR VALUE HEDGES
	Fixed-to-floating interest rate swap contracts, designated as fair value hedges, are entered into from time to time to hedge our exposure to fair value fluctuations on a portion of our fixed rate debt. We had no such contracts outstanding at March 31, 2014 or June 30, 2013.
	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 (income) expense, 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 March 31, 2014 and June 30, 2013, was $106.1 million and $102.2 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 March 31, 2014, we expect to recognize into earnings in the next 12 months $0.2 million of losses 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 March 31, 2014 and 2013, $0.5 million and $0.5 million was recognized as interest expense, respectively. During the nine months ended March 31, 2014 and 2013, $1.5 million and $1.4 million was recognized as interest expense, respectively.
	The following represents gains and losses related to cash flow hedges:
		Three Months Ended March 31,						Nine Months Ended

	Losses reclassified from accumulated other comprehensive loss into other (income) expense, net	$	340		$	425		$	1,054		$	682
	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 nine months ended March 31, 2014 and 2013.

RESTRUCTURING	'
	RESTRUCTURING
	During the December quarter, we announced our intent to implement restructuring actions to achieve synergies across Kennametal as a result of the TMB acquisition. During the March quarter we continued to implement these restructuring actions, primarily related to employment reductions. These and other restructuring actions are expected to be completed over the next three years. Total pre-tax charges are expected to be in the range of $40 million to $50 million, and are anticipated to be mostly cash expenditures.
	In conjunction with these initiatives, we recorded restructuring charges of $5.0 million during the nine months ended March 31, 2014.
	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 44 percent and 52 percent of total inventories at March 31, 2014 and June 30, 2013, respectively. Because 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.

We were in compliance with all covenants as of March 31, 2014. We had $338.7 million and $3.6 million of borrowings outstanding under the 2011 Credit Agreement as of March 31, 2014 and June 30, 2013, respectively. Borrowings under the 2011 Credit Agreement are guaranteed by our significant domestic subsidiaries. The 2011 Credit Agreement matures in April 2018.

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 that are being monitored, the matters 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 March 31, 2014 and June 30, 2013, the balances of these reserves were $11.3 million and $5.1 million, respectively. These reserves represent anticipated costs associated with the remediation of these issues. The change in the reserve was due to a $6.0 million increase related to a recent acquisition and $0.2 million of unfavorable foreign currency translation adjustments recorded during the nine months ended March 31, 2014.
	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 TAXES	'
	INCOME TAXES
	The effective income tax rate for the three months ended March 31, 2014 and 2013 was 24.1 percent and 18.5 percent, respectively. The increase was primarily driven by the impact of the American Taxpayer Relief Act of 2012 that was enacted during the prior year quarter, which extended the credit for the increasing research activities.
	The effective income tax rate for the nine months ended March 31, 2014 and 2013 was 28.5 percent and 21.7 percent, respectively. The increase was primarily driven by a $7.2 million tax charge incurred in the second quarter related to a change in assertion of a foreign subsidiary's certain undistributed earnings, which are no longer considered permanently reinvested. This change in assertion during the second quarter is related to the repatriation of $57.0 million. All earnings of other non U.S. subsidiaries are indefinitely reinvested and no deferred taxes have been provided on those earnings. This tax charge was partially offset by a lower relative U.S. current year earnings contribution.

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, restricted stock awards and restricted stock units. The difference between basic and diluted earnings per share relates solely to the effect of capital stock options, restricted stock awards and restricted stock units.
	For purposes of determining the number of diluted shares outstanding, weighted average shares outstanding for basic earnings per share calculations were increased due solely to the dilutive effect of unexercised capital stock options, unvested restricted stock awards and unvested restricted stock units by 1.0 million shares and 1.3 million shares for the three months ended March 31, 2014 and 2013, respectively, and 1.0 million shares and 1.2 million shares for the nine months ended March 31, 2014 and 2013, respectively. Unexercised capital stock options, restricted stock units and restricted stock awards of 0.2 million shares and 0.3 million shares for the three months ended March 31, 2014 and 2013, respectively, and 0.3 million shares and 1.0 million shares for the nine months ended March 31, 2014 and 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 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 that warrant a test prior to that. We noted no impairment indicators warranting additional testing.
	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				TMB Acquisition				Total
	Goodwill	$	273,757			$	598,840			$	—			$	872,597
	Accumulated impairment losses	(15,674		)		(135,168		)		—				(150,842		)

	Accumulated impairment losses	(15,674		)		(135,168		)		—				(150,842		)
	Balance as of March 31, 2014	$	262,705			$	470,941			$	240,948			$	974,594
	(1) The balance as of June 30, 2013 have been restated to reflect the change in reportable operating segments.
	The assignment of goodwill for the TMB acquisition has not yet been completed and therefore has not been allocated between the segments.
	The Company is currently exploring strategic alternatives for a portion of its Infrastructure business, which has an estimated net book value of approximately $39.0 million as of March 31, 2014.  As the evaluation is not yet complete, the Company cannot determine if an impairment loss is either probable or estimable.
	The components of our other intangible assets were as follows:
		Estimated		31-Mar-14								30-Jun-13
		Useful Life
	(in thousands)	(in years)		Gross Carrying				Accumulated				Gross Carrying				Accumulated

	Total			$	481,316			$	(132,161	)		$	334,205			$	(111,440	)
	During the nine months ended March 31, 2014, we recorded amortization expense of $18.8 million related to our other intangible assets and favorable currency translation adjustments of $3.5 million.
	On November 4, 2013, we acquired TMB from ATI, the operations of which are included in both the Industrial and Infrastructure segments. As a result of the acquisition, we increased goodwill by $240.9 million and other intangible assets by $125.3 million based on our preliminary purchase price allocations. Other intangible assets consisted of customer-related intangibles, technology-based intangibles and trademarks. We are in the process of assessing the allocation of goodwill and other intangible assets, as well as the useful lives of the other intangible assets. The majority of both the goodwill and other intangible assets will be allocated to the Infrastructure segment, as this is primarily where the operating synergies associated with the acquisition are expected to be realized. The Company estimates that acquired intangibles will add approximately $8 million to annual amortization expense per year.
	On August 1, 2013, we acquired the assets of Emura in our Infrastructure segment. As a result of the acquisition we increased other intangible assets by $16.4 million based on our preliminary purchase price allocations. We recorded supplier relationship intangible assets in technology-based and other of $15.9 million with an estimated useful life of 20 years, contract-based intangibles of $0.4 million with an estimated useful life of 3 years and trademarks of $0.1 million with an estimated useful life of 20 years. These intangible assets will be amortized over their respective estimated useful lives.
