Type 420 Metric - Left Spiral Flutes - Straight Shank
Carbide Tipped
  • Polished flutes
  • Used on thru holes for heat treated steels, hard cast irons and other hard materials
  • Finishes are much better as spiral flutes tend to bridge interruptions such as keyways, slots, or intersecting holes
  • Left spiral flutes should not be used on blind holes
  • 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
 		  Modifications: (Prompt delivery)
  • Modified tool diameter - priced below
  • 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
