Description
Resources

Constructed of M-35 5% 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° split point reduces feed pressure for easier penetration without work hardening.

7/16", 2-1/16" twist length, 3-7/16"L.
