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
