Description
Version:
Particularly sturdy version. For the highest performance demands.
Recommendation:
For very hard steels, TOOLOX and HARDOX materials we recommend deviating from the DIN data (see table) by drilling the tapping hole ⌀ 0.05 to 0.3mm larger.
For use only with a length compensation chuck − even on machines with synchronised spindle drives.
