Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION Kennametal Inc. was incorporated in Pennsylvania in 1943. Kennametal Inc. and its subsidiaries (collectively, Kennametal or the Company) are a leading global manufacturer and supplier of tooling, engineered components and advanced materials consumed in production processes. We believe that our reputation for manufacturing excellence, as well as our technological expertise and innovation we deliver in our products and services, helps us to achieve a leading position in our primary markets. End users of our products include metalworking and machinery manufacturers and suppliers across a diverse array of industries, including the aerospace, defense, transportation, machine tool, light machinery and heavy machinery, as well as producers and suppliers in a number of equipment-intensive industries such as coal mining, road construction and quarrying, as well as oil and gas exploration, refining, production and supply. Our end users' applications range from airframes to mining operations, engines to oil wells and turbochargers to processing. In order to take advantage of the growth opportunities of our WIDIA brand, we implemented a new operating structure. A key attribute of the new structure is the establishment of the WIDIA operating segment. In order to better leverage the opportunities that lie in this business, in addition to being more agile and competitive in the marketplace, we are placing higher levels of focus, determination and leadership in the business. The Industrial and WIDIA segments in 2017 were formed from the 2016 Industrial segment. We now have three global reportable operating segments: Industrial, WIDIA, and Infrastructure.

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 2016 Annual Report on Form 10-K. The condensed consolidated balance sheet as of June 30, 2016 was derived from the audited balance sheet included in our 2016 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 recurring adjustments. The results for the three months ended September 30, 2016 and 2015 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 2017 is to the fiscal year ending June 30, 2017. 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	3 Months Ended
New Accounting Standards	Sep. 30, 2016
Accounting Changes and Error Corrections [Abstract]
NEW ACCOUNTING STANDARDS	NEW ACCOUNTING STANDARDS Adopted In November 2015, the Financial Accounting Standards Board (FASB) issued guidance on balance sheet classification of deferred taxes. The amendments in this guidance require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position, in comparison to the previous practice of separating deferred income tax liabilities and assets into current and noncurrent amounts on the balance sheet. We adopted this guidance July 1, 2016 on a prospective basis. Therefore, prior period balance sheets were not retrospectively adjusted. Current deferred tax assets of $26.7 million and current deferred tax liabilities of $0.6 million are reported in the June 30, 2016 balance sheet. In April 2015, the FASB issued guidance on the presentation of debt issuance costs. The guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct reduction from the carrying amount of that debt liability, consistent with debt discounts. This guidance was effective for Kennametal beginning July 1, 2016 and was retrospectively applied to all periods presented. Debt issuance costs of $5.7 million and $6.0 million are reported as direct reductions of the carrying amounts of debt liabilities in the balance sheet as of September 30, and June 30, 2016, respectively. In April 2015, the FASB issued guidance on accounting for fees paid in a cloud computing arrangement. The amendments in this update provide guidance to customers about treatment of costs as either capitalized and amortized as an intangible asset or expensed as incurred as a service contract. The amendments provide clarification that costs in arrangements that include software license should be capitalized and amortized, and costs in arrangements that do not include a software license should be expensed as incurred. This standard was effective for Kennametal beginning July 1, 2016 and was applied prospectively. The adoption of this guidance did not have a material impact on our condensed consolidated financial position, results of operations and cash flows. Issued In August 2016, the FASB issued guidance on classification of certain cash receipts and cash payments in the statement of cash flow. The guidance addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. This guidance is effective for Kennametal beginning July 1, 2018. We are in the process of assessing the impact the adoption of this guidance will have on our condensed consolidated financial statements.

Fair Value Measurements

Fair Value Disclosures [Abstract]

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, 2016, 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⁾	$	—	$	394	$	—	$	394
Total assets at fair value	$	—	$	394	$	—	$	394

Liabilities:
Derivatives⁽¹⁾	$	—	$	518	$	—	$	518
Total liabilities at fair value	$	—	$	518	$	—	$	518

As of June 30, 2016, 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⁾	$	—	$	334	$	—	$	334

Contingent consideration	—		—		6,600		6,600
Total liabilities at fair value	$	—	$	763	$	6,600	$	7,363

⁽¹⁾ Currency derivatives are valued based on observable market spot and forward rates and are classified within Level 2 of the fair value hierarchy.

There have been no changes in classification and transfers between levels in the fair value hierarchy in the current period. The fair value of contingent consideration payable that was classified as Level 3 at June 30, 2016 related to our probability assessments of expected future milestone targets, primarily associated with product delivery, related to a previous acquisition. During the the three months ended September 30, 2016, the Company paid the remaining $6.6 million in conjunction with achieved milestone targets. The contingent consideration was recorded in other current liabilities in our condensed consolidated balance sheet at June 30, 2016. No other changes in the expected outcome have occurred during the three months ended September 30, 2016.

Derivative Instruments and Hedging Activities

3 Months Ended

Sep. 30, 2016

Derivative Instruments and Hedging Activities Disclosure [Abstract]

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)	September 30, 2016			June 30, 2016
Derivatives designated as hedging instruments
Other current assets - range forward contracts	$	239		$	323
Other current liabilities - range forward contracts	(5		)	—
Other assets - range forward contracts	35			—
Total derivatives designated as hedging instruments	269			323
Derivatives not designated as hedging instruments
Other current assets - currency forward contracts	120			11
Other current liabilities - currency forward contracts	(513		)	(763		)
Total derivatives not designated as hedging instruments	(393		)	(752		)
Total derivatives	$	(124	)	$	(429	)

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 related to derivatives not designated as hedging instruments have been recognized as follows:



	Three Months Ended September 30,
(in thousands)	2016			2015
Other expense, net - currency forward contracts	$	(318	)	$	(17	)

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, 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, 2016 and June 30, 2016, was $71.5 million and $53.3 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, 2016, we expect to recognize into earnings in the next 12 months an immaterial amount of income on outstanding derivatives.

The following represents gains and losses related to cash flow hedges:



	Three Months Ended September 30,
(in thousands)	2016			2015
(Losses) gains recognized in other comprehensive loss, net	$	(125	)	$	516
Losses (gains) reclassified from accumulated other comprehensive loss into other expense, net	$	386		$	(1,458	)

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, 2016 and 2015.

Restructuring and Related Charges

3 Months Ended

Sep. 30, 2016

Restructuring Charges [Abstract]

RESTRUCTURING AND RELATED CHARGES

We are implementing restructuring actions to streamline the Company's cost structure. These initiatives are expected to improve the alignment of our cost structure with the current operating environment through headcount reductions; rationalization and consolidation of certain manufacturing facilities; enhancement of operational efficiencies through an enterprise-wide cost reduction program; and other employment and cost reduction programs. These restructuring actions are expected to be completed by December of fiscal 2019 and are anticipated to be mostly cash expenditures.

The total pre-tax charges for these programs are expected to be in the range of $155 million to $175 million, which is expected to be approximately 60 percent Industrial, 5 percent WIDIA, 30 percent Infrastructure and 5 percent Corporate. Total restructuring and related charges since inception of $102.8 million have been recorded for these programs through September 30, 2016: $54.3 million in Industrial, $33.0 million in Infrastructure, $8.6 million in WIDIA and $6.9 million in Corporate.

We have recorded restructuring and related charges of $31.7 million and $15.1 million for the three months ended September 30, 2016 and 2015, respectively. Of these amounts, restructuring charges totaled $28.6 million and $9.1 million, respectively. During the three months ended September 30, 2016, an immaterial amount of restructuring charges was related to inventory disposals and were recorded in cost of goods sold. Restructuring-related charges of $2.0 million and $1.6 million were recorded in cost of goods sold and $1.1 million and $4.4 million in operating expense for the three months ended September 30, 2016 and 2015, respectively.

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:

STOCK-BASED COMPENSATION

Stock Options

There were no grants made during the three months ended September 30, 2016.

The assumptions used in our Black-Scholes valuation related to grants made during the three months ended September 30, 2015 were as follows:



Risk-free interest rate	1.4	%
Expected life (years) ⁽²⁾	4.5
Expected volatility ⁽³⁾	31.0	%
Expected dividend yield	2.0	%

(2) Expected life is derived from historical experience.

(3) Expected volatility is based on the implied historical volatility of our stock.

Changes in our stock options for the three months ended September 30, 2016 were as follows:



	Options		Weighted Average Exercise Price		Weighted Average Remaining Life (years)	Aggregate Intrinsic value (in thousands)
Options outstanding, June 30, 2016	2,547,809		$	33.72
Granted	—		—
Exercised	(8,359	)	22.83
Lapsed or forfeited	(90,230	)	28.36
Options outstanding, September 30, 2016	2,449,220		$	33.95	4.6	$	3,431
Options vested and expected to vest, September 30, 2016	2,413,580		$	34.02	4.6	$	3,348
Options exercisable, September 30, 2016	1,826,158		$	35.84	3.2	$	1,245

During the three months ended September 30, 2016 and 2015, compensation expense related to stock options was $0.5 million and $1.3 million, respectively. As of September 30, 2016, the total unrecognized compensation cost related to options outstanding was $2.0 million and is expected to be recognized over a weighted average period of 1.8 years.

Weighted average fair value of options granted during the three months ended September 30, 2015 was $7.17 per option. Fair value of options vested during the three months ended September 30, 2016 and 2015 was $2.6 million and $1.9 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. There were no tax benefits resulting from stock-based compensation deductions for the three months ended September 30, 2016. Tax benefits resulting from stock-based compensation deductions were less than amounts reported for financial reporting purposes by $1.4 million for the three months ended September 30, 2015.

The amount of cash received from the exercise of capital stock options was immaterial during the three months ended September 30, 2016 and 2015. There was no related tax benefit for the three months ended September 30, 2016, and the related tax benefit was immaterial for the three months ended September 30, 2015. The total intrinsic value of options exercised was immaterial during the three months ended September 30, 2016 and 2015.

Under the provisions of the Kennametal Inc. Stock and Incentive Plan of 2010 as amended and restated on October 22, 2013 and as further amended January 27, 2015, 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, 2016 and 2015 was 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 vesting date after the three-year performance period, with the exception of retirement eligible grantees, who upon retirement are entitled to vest in any units that have been earned, including a prorated portion in the partially completed fiscal year in which the retirement occurs. 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.

Changes in our time vesting and performance vesting restricted stock units for the three months ended September 30, 2016 were as follows:



	Performance Vesting Stock Units		Performance Vesting Weighted Average Fair Value		Time Vesting Stock Units		Time Vesting Weighted Average Fair Value
Unvested performance vesting and time vesting restricted stock units, June 30, 2016	115,467		$	36.96	1,014,744		$	31.97
Granted	235,241		26.35		582,219		24.98
Vested	(16,084	)	45.24		(276,114	)	36.76
Performance metric not achieved	(35,980	)	26.35		—		—

Unvested performance vesting and time vesting restricted stock units, September 30, 2016	298,644		$	28.13	1,293,019		$	27.87

During the three months ended September 30, 2016 and 2015, compensation expense related to time vesting and performance vesting restricted stock units was $8.3 million and $5.7 million, respectively. As of September 30, 2016, the total unrecognized compensation cost related to unvested time vesting and performance vesting restricted stock units was $24.2 million and is expected to be recognized over a weighted average period of 2.3 years.

Inventory Disclosure [Abstract]

INVENTORIES

We used the last-in, first-out (LIFO) method of valuing inventories for 45 percent and 44 percent of total inventories at September 30, 2016 and June 30, 2016, 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:



(in thousands)	September 30, 2016			June 30, 2016
Finished goods	$	290,530		$	284,054
Work in process and powder blends	153,944			166,274

Debt Disclosure [Abstract]
LONG-TERM DEBT	LONG-TERM DEBT The five-year, multi-currency, revolving credit facility, as amended and restated in April 2016 (Credit Agreement) permits revolving credit loans of up to $600 million for working capital, capital expenditures and general corporate purposes. The 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, 2016. We had no borrowings outstanding under the Credit Agreement as of September 30, 2016 and June 30, 2016. Borrowings under the Credit Agreement are guaranteed by our significant domestic subsidiaries. The Credit Agreement matures in April 2021. Fixed rate debt had a fair market value of $709.0 million and $704.0 million at September 30, 2016 and June 30, 2016, respectively. The Level 2 fair value is determined based on the quoted market price of this debt as of September 30, 2016 and June 30, 2016, respectively.

Environmental Matters	3 Months Ended
Environmental Matters	Sep. 30, 2016
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 Among other environmental laws, we are subject to the Comprehensive Environmental Response Compensation and Liability Act of 1980 (Superfund), under which we have been designated by the United States Environmental Protection Agency (USEPA) as a potentially responsible party (PRP) with respect to environmental remedial costs at certain Superfund sites. We have evaluated our claims and liabilities associated with these Superfund sites based upon best currently available information. We believe our environmental accruals are adequate to cover our portion of the environmental remedial costs at the Superfund sites where we have been designated a PRP, to the extent these expenses are probable and reasonably estimable. Other Environmental Matters We establish and maintain reserves for other potential environmental issues. At September 30, 2016 and June 30, 2016, the balances of these reserves were $12.5 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 Taxes	3 Months Ended
Income Taxes	Sep. 30, 2016
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The effective income tax rates for the three months ended September 30, 2016 and 2015 were 29.9 percent (provision on a loss) and 292.8 percent (provision on a loss), respectively. The change was primarily driven by a discrete tax charge in the prior year quarter for the sale of non-core businesses and a loss in the U.S. in the current quarter for which we could not record a tax benefit due to a full valuation allowance on our U.S deferred tax assets as of the fourth quarter of fiscal 2016.

Earnings Per Share	3 Months Ended
Earnings Per Share	Sep. 30, 2016
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 would occur 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 months ended September 30, 2016 and 2015, the effects of unexercised capital stock options and unvested restricted stock units were anti-dilutive as a result of net losses in the periods and therefore have been excluded from diluted shares outstanding as well as from the diluted earnings per share calculation.

Goodwill and Other Intangible Assets

3 Months Ended

Goodwill and Intangible Assets Disclosure [Abstract]

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. 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.

Identifiable assets with finite lives are reviewed for impairment when events or circumstances indicate that the carrying value may not be recoverable.

During the three months ended September 30, 2016, we reorganized our operating structure in a manner that changed the composition of our reporting units. The Industrial and WIDIA reporting units in fiscal 2017 were formed from the fiscal 2016 Industrial reporting unit. In connection with this reporting unit realignment, during the three months ended September 30, 2016 we updated our goodwill impairment assessment based on a quantitative analysis. We evaluated the goodwill of our reporting units immediately prior to and after the realignment and concluded in both cases that there was no impairment. We allocated our goodwill from the former Industrial segment to the current Industrial and WIDIA segments using a relative fair value approach. The restated Industrial reporting unit passed the goodwill impairment test with fair value substantially exceeded the carrying value. The new WIDIA reporting unit's fair value approximates its carrying value.

See Note 18 for further discussion regarding the Company's segments.

We are currently exploring strategic alternatives for one of our non-core Infrastructure businesses. The estimated net book value of the business is approximately $30 million as of September 30, 2016. As the strategic direction has not yet been determined for this business, the Company cannot determine if additional impairment charges will be incurred.

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			WIDIA			Infrastructure			Total
Gross goodwill	$	408,705		$	40,624		$	633,211		$	1,082,540
Accumulated impairment losses	(137,204		)	(13,638		)	(633,211		)	(784,053		)

We offer these products through a variety of channels to meet customer-specified needs.

The Company's reportable operating segments have been determined in accordance with the Company's internal management structure, which is organized based on operating activities, the manner in which we organize segments for making operating decisions and assessing performance and the availability of separate financial results. We do not allocate certain corporate expenses related to executive retirement plans, the Company’s Board of Directors and strategic initiatives, as well as certain other costs and report them in Corporate. None of our three reportable operating segments represent the aggregation of two or more operating segments.

The Industrial segment generally serves customers that operate in industrial end markets such as transportation, general engineering and aerospace and defense, delivering high performance metalworking tools for specified purposes. The customers in these end markets manufacture engines, airframes, automobiles, trucks, ships and various types of industrial equipment. The technology and customization requirements for customers we serve vary by customer, application and industry. The value we deliver to our Industrial segment customers centers on our application expertise and our diverse offering of products and services, with products delivered through a diverse base including direct and indirect channels.

The WIDIA segment generally serves customers that operate in industrial end markets, primarily in general engineering, delivering high performance metalworking tools for general purposes. Whereas the Industrial segment's core is in application expertise and specific customer needs, WIDIA offers a competitive alternative for general metal cutting solutions across a broader platform for application, with products delivered primarily through indirect channels.

The Infrastructure segment generally serves customers that operate in the earthworks and energy sectors who support primary industries such as oil and gas, power generation, underground, surface and hard-rock mining, highway construction and road maintenance. Generally, we rely on customer intimacy to serve this segment.
