  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:
  • These precision ground reamers should be used in pairs, .0005" and .0020" under the dowel pin diameter. The .0020" smaller holes assure a tighter dowel pin fit, so all the pins will remain on the same side upon disassembly. Especially useful in plastic or die cast molds and machines when assembled sections are subject to shearing stress, yet require occasional disassembly.
