history
In 1832 the coppersmith Robert McKenna moved from Ireland to Pittsburgh in the USA. After his death, the sons took over the business. After all of the sons died, the company was renamed McKenna Brothers Brass Company in 1899 . After an agreement with the Firth Sterling Steel Company , sales of cutting tools began in Pittsburgh and Cincinnati .
In 1900 AG McKenna developed a tool steel with 18% tungsten , which significantly increased cutting speeds in metalworking. The addition of 1% vanadium to the alloy nearly doubled the cutting speed again. In 1910, the Vanadium Alloys Steel Company (VASCO) was founded to produce vanadium alloys, with the McKenna family becoming majority shareholders. Under the direction of Roy McKay, VASCO grew strongly, especially during World War I, as the US armed forces needed tungsten steel .
In 1928 Philip McKenna became Director of Research at VASCO. He left the company in 1938 after trying tantalum carbide tools. Shortly afterwards he founded Kennametal to produce a tungsten- titanium carbide alloy that he patented . During the Second World War there was a special boom for tungsten carbide - ballistic projectiles , which significantly increased Kennametal's sales. In 1946 his company invented an indexable insert system that revolutionized the tool industry.
In 1958, Kennametal began expanding internationally. Even after Philip McKenna's death in 1969, the company continued to grow rapidly, and it went public in 1977 .
In 1993 Kennametal took over the Fürth Hertel AG and in 2002 the Widia GmbH .
