Features. Constructed of M-35 5 percent 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-degree split point reduces feed pressure for easier penetration without work hardening. Size - 316 in.. Twist Length - 1.12 in.. Overall Length - 2-316 in.
