- Constructed of M-42 8 percent cobalt high speed steel for super abrasive resistance in tough metals
- Heavy duty spiral flute design produces faster chip ejection
- Shorter cutting tip reduces 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
