Irwin 63121 Jobber Drill Bit, 21/64 in Dia, 4-5/8 in OAL, Spiral Flute, 21/64 in Dia Shank, Cylinder Shank
- 135 deg split point reduces feed pressure for easier penetration without work hardening and tip point ensures a true start and eliminates bit walking
- 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
