Item Information

A titanium nitride coating on a High Speed Steel (HSS) drill bit gives a smooth finish that significantly reduces friction while drilling. The coating extends the life of a HSS drill bit 6 times that of a rehular HSS bit

  • Use on wood, wood composites, plastics and repetitive drilling in most metals - not recommended for hard metals such as stainless steel
  • Titanium nitride coating gives an exceptionally smooth surface that reduces friction
  • Lasts up to 6 times longer than regular high speed steel drill bits
  • 135° split point tip eliminates the need for a center punch and keeps the drill bit from walking
  • 3 flats on the drill's shank insure that it is held tightly in the drill chuck
