Cobalt Drill Bits

Cobalt

  • Made with M35 steel that contains 5% cobalt for superior strength and heat resistance
  • For repetitive drilling in ferrous and non-ferrous metals and hard metals such as stainless steel
  • 135º split point tip on all drills 1/8″ diameter and larger eliminates the need for a center punch and keeps the drill from “skating” on hard surfaces
  • All sizes 3/16″ diameter and larger have 3 flats on the drill shank so the drill chuck has a secure grip
  • Fully ground drill bit
  • Extra thick drill core adds further rigidity and strength
  • Sizes available include 1/16” through 1/2” in 1/64” increments
  • Straight shank on bits 25/64” and larger is available
