Coolant hole rods programme that offers a multitude of configurations and ensures high precision

Diameter range

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. New to the range in our stock programme are ground rods with 15° helical coolant holes.

Minimum pitch tolerances

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

Extended stock range – submicron grade CTS12D

As of now our rods with helical coolant holes are also available in submicron grade CTS12D from stock. CTS12D is characterised by high wear resistance and is extremely suitable for diamond coating.
