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 three months ended September 30, 2013 and 2012 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 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 15 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.

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 September 30, 2013, 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)	$	—	$	107	$	—	$	107
	Total assets at fair value	$	—	$	107	$	—	$	107

	Total liabilities at fair value	$	—	$	862	$	14,000	$	14,862
	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:

	Total liabilities at fair value	$	—	$	530	$	—	$	530
	(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 related to the Comercializadora Emura S.R.L and certain related entities (Emura) acquisition. The contingent consideration is to be paid over the next 3 years.

Derivative_Instruments_and_Hed

Derivative Instruments and Hedging Activities	3 Months Ended
	Sep. 30, 2013
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 (income), net.
	The fair value of derivatives designated and not designated as hedging instruments in the condensed consolidated balance sheet are as follows:
	(in thousands)	September 30,			June 30,
		2013			2013
	Derivatives designated as hedging instruments
	Other current assets - range forward contracts	$	101		$	658
	Other current liabilities - range forward contracts	(853		)	(522		)
	Other assets - range forward contracts	—			69
	Total derivatives designated as hedging instruments	(752		)	205
	Derivatives not designated as hedging instruments
	Other current assets - currency forward contracts	6			48
	Other current liabilities - currency forward contracts	(9		)	(8		)
	Total derivatives not designated as hedging instruments	(3		)	40
	Total derivatives	$	(755	)	$	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 expense (income), net. Losses related to derivatives not designated as hedging instruments have been recognized as follows:
		Three Months Ended September 30,
	(in thousands)	2013			2012
	Other expense (income), net - currency forward contracts	$	42		$	1,209
	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 September 30, 2013 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 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 September 30, 2013 and June 30, 2013, was $84.7 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 September 30, 2013, we expect to recognize into earnings in the next 12 months $0.8 million of gains 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 both the three months ended September 30, 2013 and 2012, 0.5 million was recognized as interest expense.
	The following represents gains and losses related to cash flow hedges:
		Three Months Ended September 30,

	Gains (losses) recognized in other comprehensive loss, net	$	(570	)	$	(571	)
	Losses (gains) reclassified from accumulated other comprehensive loss into other expense (income), net	$	390		$	(41	)
	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 three months ended September 30, 2013 and 2012.

	During the three months ended September 30, 2013 and 2012, compensation expense related to stock options was $3.0 million and $2.8 million, respectively. As of September 30, 2013, the total unrecognized compensation cost related to options outstanding was $4.6 million and is expected to be recognized over a weighted average period of 2.9 years.
	Weighted average fair value of options granted during the three months ended September 30, 2013 and 2012 was $13.79 and $13.52, respectively. Fair value of options vested during the three months ended September 30, 2013 and 2012 was $4.5 million and $4.5 million, respectively.
	Tax benefits, relating to excess stock-based compensation deductions, are presented in the condensed consolidated statements of cash flow as financing cash inflows. Tax benefits resulting from stock-based compensation deductions exceeded amounts reported for financial reporting purposes by $3.4 million and $0.7 million for the three months ended September 30, 2013 and 2012, respectively.
	The amount of cash received from the exercise of capital stock options during the three months ended September 30, 2013 and 2012 was $8.7 million and $1.7 million, respectively. The related tax benefit for the three months ended September 30, 2013 and 2012 was $1.8 million and $0.3 million, respectively. The total intrinsic value of options exercised during the three months ended September 30, 2013 and 2012 was $6.3 million and $1.1 million, respectively.
	Under the provisions of the Kennametal Inc. Stock and Incentive Plan of 2010, 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 both the three months ended September 30, 2013 and 2012 were immaterial.
	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-year period, and are also subject to a service condition that requires the individual to be employed by the Company at the payment date after the three-year performance period, with the exception of retirement eligible grantees, who upon retirement are entitled to receive payment for any units that have been earned, including a prorated portion in the partially completed fiscal year in which the retirement occurs.

	We used the last-in, first-out (LIFO) method of valuing inventories for 51 percent and 52 percent of total inventories at September 30, 2013 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.
	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 September 30, 2013. We had $0 million and $3.6 million of borrowings outstanding under the 2011 Credit Agreement as of September 30, 2013 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.
	Fixed rate debt had a fair market value of $676.4 million and $680.1 million at September 30, 2013 and June 30, 2013, respectively. The Level 1 fair value is determined based on the quoted market price of this debt as of September 30, 2013 and June 30, 2013, 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 September 30, 2013 and June 30, 2013, the balances of these reserves were $5.2 million and $5.1 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.

	The effective income tax rate for the three months ended September 30, 2013 and 2012 was 24.6 percent and 20.7 percent, respectively. The increase was primarily driven by a favorable European audit settlement in the prior year, partially offset by a lower relative U.S. earnings contribution in the current year, as well as a favorable valuation allowance adjustment related to a state tax law change.

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, 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 1.2 million shares for the three months ended September 30, 2013 and 2012, respectively. Unexercised capital stock options, restricted stock units and restricted stock awards of 0.5 million shares and 1.1 million shares for the three months ended September 30, 2013 and 2012, 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.
