- 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 lips reduce torque for drilling in high tensile strength materials
- 135 deg split point reduces feed pressure for easier penetration without work hardening
- Ideal for use with screw extractors, made for drilling into hardened steel bolts for creating pilot hole
- 8% cobalt alloyed for higher heat and abrasion resistance
- Shorter drill for additional strength
- Drill into fasteners without tightening them
- Can often remove broken fasteners without an extractor
- Heavy duty web construction for strength and durability
