Extremely unequal pitch
- Optimal surface quality: exact, round, chatter-free countersinking
- Faster machining due to higher cutting speeds
- Significantly reduced tool wear
- Maximum running smoothness in all materials
- Much lower infeed force required
3-flat shank
No slippage, ideal for use in hand drills with 3-jaw chuck
For universal use
Almost all materials can be machined due to special tip geometry and HSCo cutting material.
Product packaging made from 100 % PCR (recycled plastic from household waste) and 100 % recyclable
