For chatter-free deburring and countersinking of holes
- The even-running cone-envelope relief grinding results in a light, paring cut
- The chip flow through the hole prevents the chips from becoming jammed in the workpiece
- Straight shank
- Product packaging made from 100 % PCR (recycled plastic from household waste) and 100 % recyclable
Notice
Not recommended for full countersinking! Increased service life and cutting performance by using drilling and cutting oil.
