Irwin 63112 3/16 Inch By 2-3/16 Inch Cobalt High Speed Steel (Case of 12)

Key Features

• 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 deg split point reduces feed pressure for easier penetration without work hardening and tip point ensures a true start and eliminates bit walking

Cobalt High Speed Steel Fractional Straight Shank Jobber Length Drill Bits are 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 begins drilling immediately, minimizing bit walk when used in applications such as metal drilling, including heavy duty abrasive alloy metal drilling on hardened heat treated steel.
