Our programme enables the production of blanks for gun drills with coolant holes in the diameter range from 3 mm to 35 mm.

Numerous versions available in stock

The optimal rods with 2, 3 or 4 coolant holes with helix angles from 15° to 46°, in standard lengths up to 530 mm can be selected for all common drill geometries.

Minimum pitch tolerances

Thanks to the unique CERATIZIT classification system even extra-long drilling tools may be ground whilst maintaining process stability.
