MCGEEHAN ANNOUNCES RETIREMENT BOARD OF DIRECTORS DISCLOSES SUCCESSION PLAN Latrobe, Pa. -- March 18, 1999 - Robert L. McGeehan, president and chief executive officer of Kennametal Inc. (NYSE: KMT), today announced that he will retire from the company effective July 1, 1999. McGeehan had confirmed his long-range objective of retiring by that date with Kennametal's Board of Directors nearly a year ago. The Board formed a special committee of the Board to oversee a smooth transition and to consider both internal and external succession candidates. "I am confident that our Board is proceeding with a well-planned transition," said Board Chairman William R. Newlin. "We have been working carefully and diligently on the succession process and expect to complete our work by our next regularly scheduled meeting, April 26, 1999." Newlin added, "Bob McGeehan has made significant contributions to Kennametal's growth and success. During his 26-year career with Kennametal and his ten years as president, Bob has led our company through enormous change. We are very grateful for the contributions he has made during his career." The special committee has already interviewed succession candidates under strict confidentiality guidelines and is in the last stage of its process. Newlin continued, "Our special board committee is doing a thorough job of implementing its transition program and in reviewing succession candidates. Kennametal has been fortunate to have had outstanding leadership during its 60 years in business and we are committed to building on our past success. Bob McGeehan's successor will have the

3 experience, talent and vision to lead Kennametal into the 21st century and extend our position as a global industry leader." McGeehan joined Kennametal in 1973 as a metalworking service engineer in Los Angeles, Calif. and served in a number of sales and marketing and general management positions during his career. He was elected president in 1989 and CEO in 1991 and is the first person from outside the McKenna family to serve Kennametal as president and CEO. Under his leadership, Kennametal's annual sales have grown from $472 million in 1989 to approximately $2 billion currently and the number of employees has grown from 5,400 to more than 14,000.
