Carbide Tipped
  • Type "C" with short carbide tip
  • Right spiral polished flutes and straight shank
  • Type "C" with flute long carbide
  • Straight polished flutes and taper shank
  • Expansion screw permits expansion of tool diameter for regrinding after wear without reinserting carbide
  • Tool geometry and carbide grade appropriate for material being machined
  • Carbide tips brazed to tough hardened alloy steel body
  • Polished flutes for easy chip flow
  • Precision ground cutting edges
  • Material specific reamer shanks are ground to next smallest shank diameter listed in NAS 897 if tool diameter is within .005" of shank diameter
  Modifications: (Prompt delivery)
  • Modified tool diameter - priced below
  • Metric tool diameter
