- Constructed of M-42 8% cobalt high speed steel for super abrasive resistance in tough metals
- Heavy-duty spiral flute design produces faster chip ejection
- Shorter cutting tips reduce torque for drilling in high tensile strength materials
- 135-degree split point reduces feed pressure for easier penetration without work hardening
- Ideal for use with screw extractors
