            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Participants and Administrator of
the Greenfield Industries, Inc. Retirement Income Savings Plan

In our opinion, the accompanying statements of net assets available for benefits
and the related statements of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the Greenfield Industries, Inc. Retirement Income Savings Plan (the "Plan")
at December 31, 2003 and 2002, and the changes in net assets available for
benefits for the years ended December 31, 2003 and 2002, in conformity with
accounting principles generally accepted in the United States of America. 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 of these statements in accordance with the
standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) is presented for the purpose of additional analysis and is not a
required part of the basic 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 basic financial statements
taken as a whole.

           GREENFIELD INDUSTRIES, INC. RETIREMENT INCOME SAVINGS PLAN
                          NOTES TO FINANCIAL STATEMENTS

                           DECEMBER 31, 2003 AND 2002

1. DESCRIPTION OF PLAN

The following general description of the Greenfield Industries, Inc. 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 employee benefit plan, established for the
purpose of providing eligible employees of Greenfield Industries, Inc. (the
Company), a wholly-owned subsidiary of Kennametal Inc., 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 (the
Code). The Plan is subject to certain provisions of the Employee Retirement
Income Security Act of 1974, as amended (ERISA). The Company serves as sponsor
of the Plan.

ADMINISTRATION OF THE PLAN - The management of the Company has the authority and
responsibility for the general administration of the Plan. Putnam Fiduciary
Trust Company serves as the Trustee of the Plan and Putnam Investment functions
as the recordkeeper for the Plan.

ELIGIBILITY - The Plan covers all non-union and certain unionized employees of
the Company. Employees may become participants in the Plan as of the first entry
date (January 1, April 1, July 1, or October 1) after completing 500 hours of
service within a six consecutive month period. 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 contributions, investments, investment gains and losses,
distributions, loans, withdrawals and transfers.

CONTRIBUTIONS - The Company is required to contribute a base amount of 2% of
each eligible employee's wages, which include base salary, overtime, shift
differential pay and incentive compensation. Effective April 1, 2003,
participants may elect to contribute to the Plan from 1% to 20% of their wages
through payroll deductions. Prior to April 1, 2003, participants could elect to
contribute to the Plan from 1% to 15% of their wages through payroll deductions.
In addition, the Company makes employer matching contributions equal to 50% of
the participant contribution up to a maximum of 2% of a participant's wages.
Employer contributions are made quarterly and solely in Kennametal Inc. common
stock. These employer contributions can be transferred to other investment
options at any time at the participant's election. Effective January 1, 2002,
employer matching contributions were temporarily suspended for all participants
except certain union employees. These contributions were reinstated January 1,
2003.

                                        5



DISTRIBUTIONS - If a participant's employment with the Company is terminated due
to retirement pursuant to the terms of the Plan, the total amount of a
participant's account shall be distributed in cash to the participant according
to one of the options as described in the Plan and as elected by the
participant. If a participant's employment with the Company is terminated for
any reason other than retirement pursuant to the terms of the Plan, the
participant will receive a lump sum amount equal to the value of the
participant's vested interest in his or her account; provided, however, that if
such account exceeds $5,000, a participant may elect to defer distribution to a
future date as more fully described in the Plan.

PARTICIPANT LOANS - Participants may withdraw certain basic contributions and
related earnings thereon only in the event of a financial hardship as defined by
the Plan or the Code. The Plan also permits participants to 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 Code. Such borrowings are allowed
at the sole discretion of the plan administrator. Loan terms range from one to
five years or up to 29 years for the purchase of a primary residence and are
secured by the balance in the participant's account. Principal and interest are
paid ratably through payroll deductions. Interest rates on participant loans
ranged from 5.0% to 10.5% at December 31, 2003 and 5.3% to 10.5% at December 31,
2002. Participant loans outstanding at December 31, 2003 have maturity dates
ranging from 2004 to 2032.

INVESTMENTS - Participants direct their contributions by electing that such
contributions be placed in a single investment fund or allocated to any
combination of investment funds. 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. The following investment options were
available to participants at December 31, 2003:

Stable Value Fund - Investments of this fixed income fund consist of traditional
investment contracts issued by insurance companies, banks and other financial
institutions (or corporations), synthetic investment contracts and short-term
investments.

Putnam Voyager Fund - This fund seeks aggressive capital appreciation by
investing in a combination of stocks of small companies expected to grow over
time as well as in stocks of larger, more established corporations.

The Putnam Fund for Growth & Income - This fund seeks growth and income by
investing in attractively priced stocks of companies that offer long-term growth
potential while also providing income.

Putnam International Growth Fund - This fund seeks capital appreciation by
investing in a diversified portfolio composed mainly of stocks of companies
located outside the United States.

Kennametal Inc. Common Stock Fund - This fund consists entirely of Kennametal
Inc. common stock, for investors who want to participate in the growth of
Kennametal Inc. as part owners of Kennametal Inc.

Vanguard Institutional Index Fund - This fund seeks long-term growth of capital
and income from dividends. The fund holds all 500 stocks that make up the
Standard & Poor's 500 Index in proportion to their weighting in the index. The
fund attempts to track the performance of the index,

                                        6



a widely recognized benchmark of U.S. stock market performance, and it remains
fully vested in stocks at all times.

PIMCO Renaissance Fund - This fund seeks long-term growth of capital and income.
The fund invests primarily in common stocks of "value" style, midsize companies
with market capitalizations of $1 billion to $10 billion at the time of
investment, although it may invest in companies of any size. The fund invests
all or a portion of its assets in small to midsize companies. Such investments
increase the risk of greater price fluctuations.

Northrop Grumman Common Stock - This fund consists entirely of Northrop Grumman
common stock for investors who want to participate in the growth of Northrop
Grumman as part owners of Northrop Grumman. This investment fund is closed to
new participants.

Retirement Ready Funds - Each Retirement Ready Portfolio has a different target
date that relates to expected retirement dates. The dates range from 2010 to
2045 in five-year intervals, with the exception of the Maturity Portfolio, which
is designed for participants who are at or near retirement. All of the
Retirement Ready Portfolios are diversified across an array of Putnam mutual
funds that invest in different styles and include a mix of stocks, bonds, and
capital preservation investments. The portfolios can invest significantly in
foreign securities, which involve certain risks, such as currency fluctuations,
economic instability, and political developments.

Artisan Mid Cap Fund - This fund seeks long-term capital growth through a
diversified portfolio of stocks of midsize companies. The fund invests all or a
portion of its assets in small to midsize companies. Such investments increase
the risk of greater price fluctuations.

MSIF Small Company Growth Portfolio - This fund seeks to maximize long-term
capital appreciation by investing primarily in the equity securities of small
and midsize companies that are in the early stages of their life cycle. The fund
invests all or a portion of its assets in small to midsize companies. Such
investments increase the risk of greater price fluctuations.

Lord Abbett Small Cap Value Fund - This fund seeks long-term capital
appreciation by investing primarily in common stocks of small companies with a
market capitalization of less than $2 billion. Lord Abbett believes in a
low-risk approach to investing in these stocks. The fund invests all or a
portion of its assets in small to midsize companies. Such investments increase
the risk of greater price fluctuations.

Vanguard Total Bond Market Index Fund - This fund invests in a sample of bonds
from the Lehman Aggregate Bond Index, which is an index of U.S. Treasury,
federal agency, mortgage-backed, and high-quality corporate securities.

In addition, during the year ended December 31, 2003, participants were able to
direct their contributions to certain other investment options. Amounts held in
the discontinued investment options were converted to available investment
options with similar investment objectives.

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 years ended December 31, 2003 and 2002, the Company paid all
expenses related to the operation of the Plan.

NET APPRECIATION / (DEPRECIATION) - Net appreciation (depreciation) of
investments is comprised of unrealized gains and losses due to the change in
market value compared to the cost of investments retained in the Plan and

USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS - The preparation of
financial statements in conformity with generally accepted accounting principles
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 these
estimates.

4.    STABLE VALUE FUND

A portion of the Plan's investments are held in a Stable Value Fund which was
established for the investment of assets of the Plan and several other
Company-sponsored retirement plans. Each plan has an undivided interest in the
underlying assets of the Stable Value Fund. The assets of the Stable Value Fund
are held by Mellon Bank, N.A. (Trustee). At December 31, 2003 and 2002, the
Plan's interest in the Stable Value Fund was 24.4 percent and 23.5 percent,
respectively. Investment income and administrative expenses relating to the
Stable Value Fund are allocated to the individual plans based upon average
monthly balances invested by each plan. The underlying assets of the Stable
Value Fund include benefit-responsive investment contracts (the contracts). The
crediting interest rates on the contracts ranged from 1.0 percent to 7.1 percent
and 1.4 percent to 7.2 percent at December 31, 2003 and 2002, respectively. The
average yields on the contracts ranged from 1.2 percent to 7.1 percent and 2.2
percent to 7.1 percent for the years ended December 31, 2003 and 2002,
respectively. The fair value of all investment contracts was $115,879,042 and
$126,432,678 at December 31, 2003 and 2002, respectively.

The Internal Revenue Service has determined and informed the plan sponsor by a
letter dated March 10, 2003, that the Plan and related trust are designed in
accordance with applicable sections of the Code.

6.    PLAN TERMINATION

Although it has not expressed any intent to do so, the Company has the right to
amend, suspend or terminate the Plan at any time, subject to the provisions of
the ERISA. In the event of Plan termination, the accounts of all participants
will become non-forfeitable.

7.    RELATED PARTY TRANSACTIONS

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

One of the investment fund options available to participants contains stock of
Kennametal Inc., the plan sponsor. The Plan held 374,101 and 344,559 shares of
Kennametal Inc. common stock at December 31, 2003 and 2002, respectively. As a
result, transactions related to this investment fund qualify as
party-in-interest transactions.
