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
3-face shank
No slippage, ideal for use in hand drills with 3-jaw chuck
Universal application
Processing of almost all materials possible thanks to special tip geometry and HSCo cutting material.
Long service life and high speed
due to super-hard coating based on titanium aluminium nitride
Sustainable product packaging made from 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified® in Bronze
