Report of Independent Registered Public Accounting Firm

To the Participants and Administrator of
the Kennametal Retirement Income Savings Plan:

We have audited the accompanying statements of net assets available for benefits of the Kennametal Retirement Income Savings Plan (the Plan) as of December 31, 2009 and 2008, and the related statement of changes in net assets available for benefits for the year ended December 31, 2009. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2009 and 2008, and the changes in its net assets available for benefits for the year ended December 31, 2009, in conformity with accounting principles generally accepted in the United States of America.

Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2009 is presented for purposes of additional analysis and is not a required part of the financial statements, but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole.

KENNAMETAL RETIREMENT INCOME SAVINGS PLAN

NOTE 1 - DESCRIPTION OF PLAN

The following general description of the Kennametal Retirement Income Savings Plan, as amended (the Plan), is provided for general information purposes only. Participants should refer to the plan document for complete information.

The Plan is a defined contribution plan, established to encourage investment and savings for eligible union employees of Kennametal Inc. (Kennametal or the Company), and to provide a method to supplement their retirement income. The Plan provides these employees the opportunity to defer a portion of their annual compensation for federal income tax purposes in accordance with Section 401(k) of the Internal Revenue Code, as amended (IRC). The Plan also provides for Company contributions. The Plan is subject to certain provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). The Company serves as the Plan sponsor.

ADMINISTRATION OF THE PLAN – The management of the Company has the authority and responsibility for the general administration of the Plan. Fidelity Management Trust Company functions as the trustee, and Fidelity Investments Institutional Operations Company functions as the recordkeeper.

ELIGIBILITY – Employees are participants in the Plan on the first day of the first payroll period subsequent to completing six (6) months of service. Under present federal income tax law, employer contributions and all earnings of the Plan do not constitute taxable income to the participants until withdrawn from the Plan by the participants.

VESTING – All participant and employer contributions vest immediately.

PARTICIPANT ACCOUNTS – A separate account is maintained for each participant in the Plan, reflecting investments, contributions, investment gains and losses, distributions, loans, withdrawals and transfers.

CONTRIBUTIONS – The Company is required to contribute quarterly, a base amount of 2% of each eligible employee’s wages, which include base salary, overtime, shift differential pay and incentive compensation. Participants may elect to contribute to the Plan from 1% to 20% of their pre-tax wages through payroll deductions. Employees who are age 50 or older and who exceed the annual dollar limit under the law or the Plan are eligible to make catch-up contributions. Unless otherwise amended, the Plan provides for employer matching contribution of 50% of employee contributions up to 4%. As such, the maximum employer matching contribution is 2%. Under the Plan, the Company has the discretion to make its employer matching contributions in Kennametal common stock.

The participants can elect to have their contributions (pre-tax, catch-up and rollover amounts) invested in the different investment funds available under the Plan. Currently, the Plan offers 23 mutual funds, Kennametal Common Stock, and a Master Trust. Employer mandatory and matching contributions are made quarterly. During January and February 2009, prior year employer contribution receivable was invested in the same investment fund elections that the employee elected for their pre-tax or after-tax contributions. Effective March 1, 2009 employer contributions were made in Kennametal common stock.

DISTRIBUTIONS – Distributions to participants due to disability, retirement or death are payable in either a lump sum or in periodic payments for a period not to exceed ten (10) years. If a participant’s vested interest in his or her account exceeds $1,000, a participant may elect to defer distribution to a future date as more fully described in the plan document.

In addition, while still employed, participants may withdraw pre-tax employee and Company contributions if over age 59.5, at any time. Pre-tax employee and Company contributions can be withdrawn by participants under age 59.5 only for specific hardship reasons.

PARTICIPANT LOANS – Participants may borrow from their accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 less the excess of the highest outstanding loan balance during the previous one-year period over the outstanding balance as of the date of the loan or 50% of their account balance as defined by the Plan or the IRC. Principal and interest are paid ratably through payroll deductions. The maximum term permissible for a general-purpose loan is 5 years and 30 years for a residential loan. The interest rate is determined by the plan administrator based on existing market conditions and is fixed over the life of the loan. Interest rates on participant loans ranged from 4.25% to 9.25% at December 31, 2009 and 5.0% to 9.5% at December 31, 2008. Participant loans outstanding at December 31, 2009 have maturity dates ranging from 2010 to 2039.

INVESTMENTS – Participants direct their contributions and Company cash contributions by electing that such contributions be placed in a single investment fund or allocated to any combination of investment funds available under the Plan. Earnings derived from the assets of any investment fund are reinvested in the fund to which they relate. Participants may elect at any time to transfer all or a portion of the value of their accounts among the investment funds.

For Company contributions made in Kennametal common stock, participants have the ability to exchange the Kennametal common stock for a single investment fund or for any combination of investment funds under the Plan.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF ACCOUNTING – The financial statements of the Plan are prepared under the accrual method of accounting.

As described in Accounting Standards Codification (ASC) 946-210, “Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined-Contribution Health and Welfare and Pension Plans,” investment contracts held by a defined-contribution plan are required to be reported at fair value. However, contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined-contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. As required by this standard, the statements of net assets available for benefits present the fair value of the investment contract as well as the adjustment of the fully benefit-responsive investment contract from fair value to contract value. The statements of net assets available for benefits are prepared on a contract value basis.

RECENT ACCOUNTING PRONOUNCEMENTS

As of December 31, 2009, the Plan adopted ASC 105-10, “The Financial Accounting Standards Board (FASB) Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles.” The FASB Accounting Standards Codification (Codification) is the single source of authoritative nongovernmental accounting principles generally accepted in the United States of America (U.S. GAAP). The Codification does not change current U.S. GAAP, but is intended to simplify user access to all authoritative U.S. GAAP by providing all of the authoritative literature related to a particular topic in one place. All existing accounting standard documents will be superseded and all other accounting literature not included in the Codification will be considered non-authoritative. The Codification affects the way entities reference U.S. GAAP in financial statements and in their accounting policies.

In January 2010, the FASB issued Accounting Standards Update (ASU) 2010-06, “Fair Value Measurements and Disclosures (Topic 820) – Improving Disclosures about Fair Value Measurements” (ASU 2010-06). ASU 2010-06 requires new disclosures for fair value measurements and provides clarification for existing disclosures requirements. More specifically, this update will require (a) an entity to disclose separately the amounts of significant transfers in and out of Levels 1 and 2 fair value measurements and to describe the reasons for the transfers; and (b) information about purchases, sales, issuances and settlements to be presented separately (i.e. present the activity on a gross basis rather than net) in the reconciliation for fair value measurements using significant unobservable inputs (Level 3 inputs). This update clarifies existing disclosure requirements for the level of disaggregation used for classes of assets and liabilities measured at fair value and requires disclosures about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements using Level 2 and Level 3 inputs. The new disclosures and clarifications are effective for the Plan beginning January 1, 2010, except for the disclosures about purchases, sales, issuances and settlements in the roll forward of activity in Level 3 fair value measurements. Those disclosures are effective beginning January 1, 2011.

As of December 31, 2009, the Plan adopted ASC 820-10, “Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly.” ASC 820-10 provides guidance on factors to be considered while estimating fair value in accordance with ASC 820-10, “Fair Value Measurements and Disclosures,” when there has been a significant decrease in market activity for an asset or liability. This guidance retains the existing “exit price” concept under ASC 820-10 and therefore does not change the objective of fair value measurements, even when there has been a significant decrease in market activity. ASC 820-10 also provides additional guidance on disclosure requirements for defining the major categories of debt and equity securities and the valuation techniques used to measure fair value. See Note 3 for additional disclosures.

As of December 31, 2009, the Plan adopted ASU 2010-09, “Subsequent Events (Topic 855) – Amendments to Certain Recognition and Disclosure Requirements.” The FASB has amended its guidance on subsequent events to remove the date through which an entity has evaluated subsequent events. ASU 2010-09 is effective upon issuance. ASU 2010-09 did not have an impact on the Plan’s financial statements.

In April 2009, the FASB issued ASC 320-10, “Recognition and Presentation of Other-Than-Temporary Impairments.” ASC 320-10 contains a new method for recognizing and reporting other-than-temporary impairments of debt securities. It also contains additional disclosure requirements for investments in debt and equity securities. ASC 320-10 did not have an impact on the Plan’s financial statements.

In March 2008, the FASB issued ASC 815-10, “Disclosures about Derivative Instruments and Hedging Activities.” ASC 815-10 expands the current disclosure requirements for derivative instruments and hedging activities. ASC 815-10 did not have an impact on the Plan’s financial statements.

USE OF ESTIMATES – The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results may differ from those estimates.

INVESTMENTS – Investment transactions are recorded on a trade date basis. INVESCO Institutional, Inc. reported that all the investment contracts held in the Master Trust under the Stable Value Fund (see Note 5) are fully benefit-responsive. Fully benefit-responsive investment contracts are reported at fair value under investments with a corresponding adjustment to contract value for purposes of reporting net assets available for investments in accordance with the provisions of ASC 946-210. Shares of mutual funds are valued at the net asset value of shares held by the Plan at year-end. Investments in Kennametal common stock are valued at their quoted market price at year-end. Participant loans are valued at amortized cost, which approximates fair value.

PAYMENT OF BENEFITS – Benefit payments are recorded when paid to participants / beneficiaries.

INVESTMENT INCOME – Interest and dividend income are recorded in the period earned.

NET APPRECIATION – Net appreciation in fair value of investments is composed of unrealized gains and losses, which represent the change in market value compared to the cost of investments in each year, and realized gains and losses on security transactions, which represent the difference between proceeds received and average cost. Net appreciation in fair value of investments for the year ended December 31, 2009 was as follows:

		2009
Kennametal Inc. Common Stock		$	294,489
Mutual Funds			1,410,466
Total		$	1,704,955

PLAN EXPENSES – Expenses attributable to the administration or operation of the Plan and related trust are allocated pro rata on the basis of account balances to the accounts of participants unless the Board of Directors of the Company, at its sole discretion, determines that such expenses are to be paid by the Company. For the year ended December 31, 2009, the Company paid substantially all administrative expenses related to the operation of the Plan. Investment management fees and costs incurred in connection with the purchase and sale of securities are equitably apportioned among the respective investment funds. These expenses are included as a deduction from net assets in the statement of changes in net assets available for benefits.

NOTE 3 - 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 distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). Fair value measurements are assigned a level within the hierarchy based on the lowest significant input level. The three levels of the fair value hierarchy are described 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.

The following sections describe the valuation methodologies used by the Plan to measure investments at fair value, including an indication of the level in the fair value hierarchy in which each major category of investments is generally classified. Where appropriate, the description includes details of the valuation models and any significant assumptions.

Mutual Funds Investments in mutual funds are valued at quoted net asset values at year end.

Master Trust The plan has an undivided interest in the underlying assets of the Master Trust. Assets of the Master Trust are held in a stable value fund by INVESCO. The Master Trust primarily invests in wrapper contracts, or synthetic guaranteed investment contracts. See Note 5 for additional disclosures related to the Master Trust. The fair value of the underlying assets of the Master Trust were determined using a present value model and the principal inputs are discount rate, fee periods, fee invoice schedule, contract value, replacement cost and actual cost.

Common Stock Investments in common stock are valued at their quoted market price at year-end.

Participant Loans Participant loans are valued at amortized cost, which approximates fair value.

As of December 31, 2009, the fair values of the Plan’s investments measured on a recurring basis are categorized as follows:

		Level 1				Level 2				Level 3				Total

		2009				2008

MSIFT MidCap Growth Portfolio			948,035				677,368
H&W LargeCap Value Fund			779,757				611,279

NOTE 5 - MASTER TRUST

A portion of the Plan’s investments are held in a Master Trust, which was established for the investment of assets of the Plan and two other Company-sponsored defined contribution plans. Each plan has an undivided interest in the underlying assets of the Master Trust. The assets of the Master Trust are held in a stable value fund by INVESCO. Investment income relating to the Master Trust is allocated to the individual plans based upon average monthly balances invested by each plan. The underlying assets of the Master Trust include benefit-responsive investment contracts (the contracts).

The Master Trust’s key objectives are to provide preservation of principal, maintain a stable interest rate, and provide daily liquidity at contract value for participant withdrawals and transfers in accordance with the provisions of the Plan.

To accomplish the objectives described above, the Master Trust primarily invests in wrapper contracts, or synthetic guaranteed investment contracts (GICs). In wrapper contracts, the investments are owned and held by the Master Trust for Plan participants. The Trust purchases a wrapper contract from an insurance company or bank. The wrapper contract amortizes the realized and unrealized gains and losses on the underlying fixed-income investments, typically over the duration of the investments, through adjustments to the future interest-crediting rate, the rate earned by participants in the Master Trust for the underlying investments. The issuer of the wrapper contract provides assurance that the adjustment to the interest-crediting rate will not result in a future interest-crediting rate that is less than zero. An interest-crediting rate less than zero would result in a loss of principal or accrued interest.

The key factors that influence future interest-crediting rates for a wrapper contract include the level of market interest rates, the amount and timing of participant activity within the wrapper contract, the investment returns and the duration of the underlying investments. Most wrapper contracts use a formula based on the characteristics of the underlying fixed-income portfolio to determine a crediting rate. Over time, the crediting rate formula amortizes the Master Trust’s realized and unrealized market value gains and losses over the duration of the investments. The wrapper contracts’ interest-crediting rates are typically reset on a monthly or quarterly basis.

The average yield earned by the Plan based on actual earnings was 3.10% and 7.14% for the years ended December 31, 2009 and 2008, respectively. The average yield earned by the Plan based on the interest rate credited to participants was 4.07% and 4.21% for the years ended December 31, 2009 and 2008, respectively.

In certain circumstances, the amount withdrawn from the wrapper contract would be payable at fair value rather than at contract value. These events include termination of the Plan, a material adverse change to the provisions of the Plan, if the employer elects to withdraw from a contract in order to switch to a different investment provider, or if the terms of a successor plan do not meet the wrapper contract issuer’s underwriting criteria for issuance of a clone wrapper contract. Management believes that the events described above could result in the payment of benefits at fair value rather than contract value and are not probable of occurring in the foreseeable future.

NOTE 6 - TAX STATUS

The Plan obtained its latest determination letter on March 10, 2003, in which the Internal Revenue Service stated that the Plan, as then designed, was in compliance with the applicable requirements of the IRC. The Plan has been amended since receiving the determination letter. However, the Plan administrator and the Plan’s tax counsel believe that the Plan is currently designed and being operated in compliance with the applicable requirements of the IRC. Therefore, no provision for income taxes has been included in the Plan’s financial statements.

NOTE 7 - PLAN TERMINATION

Although it has not expressed any intent to do so, the Company has the right to suspend or terminate the Plan at any time, subject to the provisions of the ERISA and according to the terms of the collective bargaining agreement.

NOTE 8 - RISKS AND UNCERTAINTIES

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits.

NOTE 9 - RELATED PARTY TRANSACTIONS

Certain investments of the Plan are mutual funds managed by Fidelity Investments. The trustee of the Plan is Fidelity Management Trust Company and, therefore, these transactions qualify as party-in-interest transactions.

One of the investment fund options available to participants is common stock of Kennametal Inc., the Plan sponsor. The Plan held 70,375 and 69,527 shares of Kennametal common stock, or $1,825,158 and $1,587,724 at December 31, 2009 and 2008, respectively. As a result, transactions related to this investment fund qualify as party-in-interest transactions.
