Features and benefits

  • The all new KMH solid carbide drills are engineered for hard material applications up to 65 HRC. The B95_ drill series with through coolant and 140° point is designed for deeper applications.

  • KMH Point Design with curved cutting edge with corner chamfer for maximum corner stability in hard materials. It avoids chipping on cutting edge thus pre-mature wear.

  • Special flute design with strong web to increase the strength of the drill in tough applications with short chips. B95_ series with 30° helix angle to improve chip evacuation in higher length-to-diameter ratios.

  • KCH15 on B95_ with its higher toughness supports edge strength at increased rake angles, which are applied to improve chip evacuation in higher L/D ratios. It carries a high temperature and shock resistance AlTiN coating for machining hardened material to increase tool life.
