Type 414 Fractional - Center Fed For Blind Holes - For Non-Ferrous Materials
Carbide Tipped
  • Center coolant outlet
  • Polished flutes; flute long carbide on .2841" tool diameter and larger
  • 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
  • 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:
  • Center coolant outlet for reaming blind holes as chips are flushed back towards the shank
  • Improves hole finish and permits higher feeds & speeds with longer tool life
