Applications

The 60° countersinking tool opens up flexible application possibilities in professional manufacturing. It is primarily designed to chamfer and deburr drilled holes in steel, stainless steel, cast iron, and non-ferrous metals. Thanks to its smooth cutting action, it is highly suitable for both batch production and general workshop tasks where clean edges are required.

Special features

The combination of a 60° angle and a three-flute geometry creates favorable conditions for controlled and quiet machining without chatter marks. The HSSCo8 substrate provides enhanced temperature resistance due to its cobalt content, which supports consistent performance in challenging materials. Furthermore, the cylindrical shank ensures reliable torque transmission during operations.
