Description
Version:
For roughing and finishing. Up to 1.5×D into solid material at very high feed rates with smooth cutting action. Optimised end face geometry.
Application:
- Optimised flute form, eccentric relief ground.
- Large flute profiles.
- Improved chip evacuation due to optimised end face geometry.
- Minimal wear due to sturdy cutting edges.
