Features:

• 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

Applications:

For tough metal drilling applications
