Composition: PVD AlTiN coated, fine-grain carbide.
Application: First choice for hardened steels between 48 and 55 HRC as well as case-hardened workpieces with hole depths >3 x D.

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.
