Irwin Cobalt Drill Bits 29-Piece Set

Description

Constructed of M-35 5% cobalt alloy high speed steel which extends and maintains cutting edge life. The 135° split point tip starts on contact and cuts with less force. Reduced shank above 3/8" allows the use of larger drill bits in a 3/8" chuck. Rubber overmolded case protects kit if dropped.

• Tap and drill selection chart for convenient reference
• Automatic indexing for easy bit access and identification
• Removable cartridges make it easy to carry bits from case to project
