Type 462 Fractional - For Cast Irons & NAS Multi-Purpose
Carbide Tipped
  • 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
  • Geometry and carbide grade appropriate for material being machined
  • Carbide tips brazed to tough hardened alloy steel body, except expansion reamers which are not hardened
  • 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
Use:
  • Expansion reamers are recommended for reaming abrasive materials. As the diameter wears down, the reamers can be expanded many times by tightening the end expansion screw and regrinding to its original size. Expansion reamers should not be considered as adjustable for use in producing holes of different sizes.
