History

Innovation, perseverance and close attention to customer needs have characterized Kennametal since its founding. In 1938, after years of research, metallurgist Philip M. McKenna created a tungsten-titanium carbide alloy for cutting tools that provided a productivity breakthrough in the machining of steel. "Kennametal®" tools cut faster and lasted longer, and thereby facilitated metalworking in products from automobiles to airliners to machinery. With his invention, Philip started the McKenna Metals Company in Latrobe, Pennsylvania. Later renamed Kennametal, the corporation has become a world leader in the metalworking industry and remains headquartered in Latrobe.

McKenna Metal's first full-year sales, with a staff of 12 employees, totaled some $30,000. But World War II saw American heavy industry shift into high gear. Kennametal's annual sales approached $10 million and employment was nearly 900 as the company's tools were used extensively in the war-time economy.

When the wartime boom ended, Kennametal sought new ways to exploit the toughness and wear resistance of tungsten carbide alloys. In the mid-1940s, the company pioneered the use of carbide tooling for mining, which led to the development of the continuous mining machine. Kennametal also found uses for tungsten carbide in demanding specialty applications where resistance to wear was vital, such as in valves, dies, drill bits and snowplow blades.

Kennametal was founded on the strength of a technological breakthrough, and a list of highlights demonstrates that it has continued to lead its industry in innovation.

In 1946, the company introduced the Kendex line of mechanically held, indexable insert systems that accelerated tool changing and increased machining precision.

Kennametal's unique, patented thermit process for producing impact-resistant macrocrystalline tungsten carbide today remains the best way to produce extremely tough tool materials for demanding applications such as mining.

In 1964, Kennametal introduced tungsten-carbide-tipped Kengrip tire studs. Although studs clearly contributed to safe winter travel, they became controversial amid speculation about their role in road deterioration. After legislation limited the use of carbide studs, Kennametal left the business in 1977.

Leader in the development of silicon-nitride based "sialon" ceramics for the machining of exotic aerospace materials.

First to develop cobalt-enriched substrates for coated inserts, was first to commercially introduce physical-vapor-deposition (PVD) coated cemented carbide cutting tools and created the first commercially viable diamond-coated carbide inserts.

Leader in the development of quick-change tooling systems that today lead the world in versatility, speed and accuracy.

Kennametal maintains its technological leadership through its $30-million Technology Center in Latrobe, Pennsylvania, and complementary facilities in various locations around the globe. The facilities are dedicated to rapid development of products engineered to meet specific customer requirements.
