Remark: * Vc max. corresponds either to the max. permissible spindle speed for this fine boring head (20 000 rpm), or to the max. cutting speed for the machining of the corresponding workpiece material.
For cutting with high spindle speeds (> 10 000 rpm), the complete and pre-set tool assembly has to be fine balanced. For all operations we recommend to use a fine balanced tool shank.
