National Aerospace Standards - NAS 897
Type 482 Fractional - For Non-Ferrous Materials
Carbide Tipped
  • Type "C" with flute long carbide
  • Left spiral polished flutes and straight shank
  • Left spiral flutes should not be used on blind holes
  • 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
  • Metric tool diameter
  • Closer tool diameter tolerance
  • Cutting diameter reduced for step or pilot
  • End chamfer other than 45º
  • End cutting or corner radius
  • Increased / decreased circular margin
  • Increased / decreased tool diameter back taper
  • Shortened shank or reduced shank diameter
  • Flat(s) or tang on shank
  • Coatings available:
