Type 2428 Fractional
Tools - Reamers - Coolant Fed Reamers - Coolant Fed Reamers with Left Spiral Flutes and Flute Fed Coolant for Through Holes

Description

  • Coolant outlets in each flute
  • Polished flutes; flute long carbide on .2841" tool diameter and larger
  • 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

Options

  • 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
  • Shortened shank or reduced shank diameter
  • Flat(s) or tang on shank
Coatings available:
  • TITANIUM NITRIDE - TiN
  • TITANIUM CARBONITRIDE - TiCN
  • ZIRCONIUM NITRIDE - ZrN
  • AL TITANIUM NITRIDE - AITiN

Use

  • Flute coolant outlets for reaming thru holes as chips are flushed forward through the hole being reamed
  • Improves hole finish and permits higher feeds & speeds with longer tool life
