Irwin 63118 9/32 Inch By 2-11/16 Inch Cobalt High Speed Steel (Case of 6)

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.

High-speed steel with M-35, 5% cobalt, for higher heat and abrasion resistance; heavy-duty web construction for strength and durability. 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 steel (heat-treated).
