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.
