IRWIN 63111 Jobber Drill Bit, 11/64 in Dia, 3-1/4 in OAL, Spiral Flute, 11/64 in Dia Shank, Cylinder Shank

Product Overview

• 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).
• bullet: Constructed of M-35 5% cobalt high-speed steel for super abrasive resistance in tough metals
• bullet: Heavy-duty spiral flute design produces faster chip ejection
• bullet: Shorter cutting lips reduce torque for drilling in high tensile strength materials
• bullet: 135 deg split point reduces feed pressure for easier penetration without work hardening and tip point ensures a true start and eliminates bit walking
