Extremely uneven pitch
- Maximum surface quality: exact, round, chatter-free countersinks
- Faster processing thanks to higher cutting speeds
- Greatly reduced tool wear
- Maximum smoothness in all materials
- Much less feed force required
For universal use
Processing of almost all materials possible thanks to special tip geometry and HSCo cutting material.
