Type 474 Fractional - For Steels & High Temp Alloys
Carbide Tipped
  • Type "C" with short carbide tip
  • Straight polished flutes and taper shank
  • 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
  • “Taper Shank No.” refers to American Standard taper series (formerly Morse taper series) per ASME/ANSI B5.10
  • 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
  • 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
  • Shank whistle notch for set screw
  • Smaller taper shank
  • Coatings available:
