Description

Constructed of M-42 8% cobalt high speed steel for super abrasive resistance in tough metals. Heavy-duty spiral flute design produces faster chip ejection. Shorter cutting lips reduce torque for drilling in high-tensile strength materials. 135 deg. split point reduces feed pressure for easier penetration without work hardening. Carded.
