Features and benefits

  • The B94_ drill series without through coolant is specifically designed to machine hardened and surface hardened materials, using flood coolant. With its 145° point angle, it is also perfectly suited as pilot drill for the B95_ drill series with through coolant and 140° point 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. B94_ series with 15° helix angle to maximize stability in applications above 54 HRC.

  • Grade KCH10 on B94_ series consists of a special fine grain carbide substrate with higher hardness. It carries a high temperature and shock resistance AlTiN coating for machining hardened material to increase tool life.
