Description

  • Coolant outlets in each flute
  • Flute long carbide
  • Polished flutes
  • Tool geometry and carbide appropriate for material being machined.

Modifications

  • End chamfer other than 45°
  • End cutting or corner radius
  • Increased/Decreased back taper
  • Closer tool diameter tolerance (.0001")
  • Cutting diameter reduced for step or pilot (Some modifications may affect the TIR)
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 hold being reamed
  • Improves hole finish and permits higher feeds and speeds with longer tool life
