KMH solid carbide drills are engineered for hard material applications up to 65HRc. The B941 series consists of a special fine-grain carbide substrate with extreme high hardness properties. The 15° helix angle maximises stability in applications above 54HRc whilst the high temperature and shock resistant AlTiN coating provides outstanding tool life.An increased core strenghtens the drill and the curved cutting edge with corner chamfer prevents chipping.
