Kennametal has introduced an expansion of its solid carbide drilling portfolio, the HPR drill for highperformance drilling of cast iron workpieces. Designed for high-speed and high-feed drilling up to 8 x D in any ISO-K material, the HPR drill provides excellent hole straightness even at highest cutting parameters.
Winning features
The drill’s patented point thinning, special gashing, and a 143°-point angle provide excellent selfcentering capabilities and reduce thrust, keeping the drill running straight even at the highest feed rates. In addition, four margin lands deliver maximum stability when drilling cross holes and inclined exits.
