Accounting Changes and Error Corrections [Abstract]
NEW ACCOUNTING STANDARDS	NEW ACCOUNTING STANDARDS Adopted As of July 1, 2012, Kennametal adopted the Financial Accounting Standards Board (FASB) deferral to present reclassifications of other comprehensive income on the face of the income statement. Companies were still required to adopt the other requirements contained in the accounting guidance on presentation of other comprehensive income. The adoption of this guidance did not have an impact on our condensed consolidated financial statements. As of July 1, 2012, Kennametal adopted changes to the presentation of comprehensive income. This guidance eliminated the option to report other comprehensive income and its components in the statement of changes in equity. An entity could elect to present items of net income and other comprehensive income in one continuous statement or in two separate consecutive statements. Each component of net income and other comprehensive income, together with totals for comprehensive income and its two parts, net income and other comprehensive income, need to be displayed under either alternative. We elected to present the two-statement option. Other than the change in presentation, the adoption of this guidance had no impact on the condensed consolidated financial statements. As of July 1, 2012, Kennametal adopted changes to testing goodwill 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 a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The adoption of this guidance did not have an impact on our condensed consolidated financial statements. Issued In June 2012, the FASB issued 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 the indefinite lived intangible assets is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step impairment test. This guidance is effective for Kennametal beginning July 1, 2013, with early adoption permitted.
