Superior to Cobalt bits, cryogenic treatment drill bits are the latest cutting edge technology! Cryogenic treatment creates a more uniform "grain" structure by transforming retained austenite into martensite. Modified carbon micro-structure through precipitation of carbides makes these bits extremely sharp and resistant to wear. Norseman CN-Tech Drill Bits are cryogenically frozen to -300 degrees fahrenheit for 48 hours, which reduces the brittleness of the drill bits, increasing strength and decreasing the chance of the bit shearing.

  • Type 190-CN High Speed Steel CN-Tech Jobber Length Bits - 5 Pack
  • Cryogenic treatment results in longer tool life and makes the bits harder and stronger
  • Three flats ground onto sides of shank to reduce the slippage of the bit when used in drill chucks
  • Precision ground points, flutes, body, clearance and drill diameter for accurate and precise cutting
  • 135 Degree Split Point - USA MADE
