KENNAMETAL CONTINUES STRONG GROWTH TREND IN THIRD QUARTER

– Sales up 14 percent over last year

– Reported earnings per diluted share of $0.66, up 144 percent over last year

– Strong cash flow

LATROBE, Pa., April 28, 2004 - Kennametal Inc. (NYSE: KMT) today reported fiscal 2004 third-quarter earnings of $0.66 per diluted share compared with reported earnings of $0.27 per diluted share last year and exceeding previous guidance provided for the quarter. There were no special items to report in the fiscal 2004 third quarter, which was 74 percent above last year’s comparable earnings per diluted share of $0.38, excluding special items.

Earnings Per Share

Original Company Guidance (1/28/04)	$0.50 to $0.60
(Updated to $0.65 on 4/19/04)
Analyst Estimate Range (4/16/04)	$0.52 to $0.60
Earnings Per Share	$0.66

For the first nine months of fiscal 2004, reported earnings of $1.20 per diluted share compared with earnings of $0.65 per diluted share last year. Excluding special items in each period, diluted earnings of $1.34 per share were 40 percent above the prior year’s comparable earnings of $0.96 per share.

Kennametal Chairman, President and Chief Executive Officer, Markos I. Tambakeras, said, “We were pleased to deliver a quarter of strong earnings growth, as improving markets combined with the implementation of the Kennametal Value Business System (KVBS) by Kennametal employees allowed us to leverage the many improvements we have made to our business. Investments in product innovation, marketing

initiatives, and acquisitions allowed us to outperform several of our end markets. This improvement was broad-based, and included Metalworking North America and Rest-of-World, Mining and Construction and Energy, and the J&L distribution business. In addition to the top-line growth, our earnings benefited from our streamlined cost structure.”

Highlights of the Fiscal 2004 Third Quarter

• Sales of $524 million were 14 percent above the prior year comparable quarter primarily on 6 percent organic sales growth, 2 percent from additional workdays, and 6 percent benefit from foreign currency exchange rates.

• Reported net income was $24.1 million versus net income of $9.7 million in the same quarter last year. Reported net income grew 80 percent compared to net income excluding special items of $13.3 million last year, reflecting the benefits of increased volume, mix, and a leaner cost structure.

• Net cash flow from operations was $54 million, versus $40 million for the prior year. Free operating cash flow totaled $41 million for the quarter, versus $26 million in last year’s comparable quarter due largely to the improved operating performance.

• As of March 31, 2004, total debt was $494 million, down $31 million from June 2003, and $86 million below March 2003.

• Debt to capital decreased to 37 percent, from 43 percent at the end of March in the prior year.

• Concluded the acquisition of Conforma Clad Inc.

Highlights of First Nine Months of Fiscal 2004

• Sales of $1.4 billion were 10 percent above the prior year comparable period on a 2 percent improvement from organic sales growth, 3 percent incremental sales from acquisitions, and a 5 percent improvement from foreign currency exchange rates.

• Reported net income totaled $43.7 million versus $23.0 million in last year’s comparable period, a 90 percent increase. Excluding special items in both periods, net income improved 43% to $48.5 million in the current nine-month period.

Outlook

Tambakeras said, “Entering the final quarter of our year, we are optimistic that the momentum we built through the March quarter will continue, with strong sequential earnings growth in the June quarter. We anticipate that improvement in North American markets will increase, Europe will remain fairly stable and the developing markets will sustain recent high growth rates. Further, we expect that the Kennametal Value Business System (KVBS) will support additional outperformance.”

Sales for the fourth quarter of fiscal 2004 are expected to grow 10 to 12 percent year-over-year, including the impact of currency. Organic growth is anticipated to be 6 to 8 percent year-over-year. Reported diluted earnings per share are expected to be $0.70 to $0.80 per share, up 56 to 78 percent compared to the prior year.

Based on forecasted results for the fourth quarter, reported diluted earnings per share are expected to be $1.90 to $2.00 per share for fiscal 2004. This includes net special charges to date of approximately $0.14 per share. Excluding these charges, diluted earnings per share are forecasted to range from $2.05 to $2.15 per share. As previously stated, the earnings outlook for the full year includes approximately $0.12 per share of accretion from the Widia acquisition.

Kennametal anticipates net cash flow provided by operating activities of approximately $155 to $175 million in fiscal 2004. Purchases of property, plant and equipment, net of proceeds from disposals of property, plant and equipment are expected to be approximately $50 to $55 million. Adjusting net cash flow provided by operating activities for the above items, Kennametal expects to generate between $100 and $125 million of free operating cash flow for fiscal 2004.

Kennametal advises shareholders to note monthly order trends, for which the company makes a disclosure ten business days after the conclusion of each month. This information is available on the Investor Relations section of Kennametal’s corporate web site at www.kennametal.com.
