  • MAINTENANCE LENGTH – Reduced overall length provides increased rigidity, strength and breakage resistance.
  • MULT-PHASE CRYOGENIC TREATEMENT – Patented deep thermal cycle brings drills down to -300°F to alter and refine the molecular grain structure, relieve stress fracturing and increase durability & life.
  • STABILIZED MOLECULAR STRUCTURE – Cryogenic treatment reduces brittleness and provides extended tool life.
  • “N” SERIES NITRIDE TREATMENT – Nitride treatment case hardens the cutting surfaces for superior edge retentions, faster long-term hole creation and longer service life.
  • BROKEN FASTENER REMOVAL – The left hand drill rotation can cause a fastener to back out when drilling, eliminating the need to use screw extractors to remove broken fasteners.
  • 135° SPLIT POINT – Super heavy-duty 135° split point eliminates center punching.
  • PREMIUM “M” SERIES ALLOY STEEL – Provides exceptional wear resistance and extremely long tool life.
  • FLATTED SHANKS – Precision ground flats on the shank eliminate drill slippage and prevents damage to the drill and chuck. (Sizes smaller than 3/16" do not have flatted shanks).
