Applications

This spotting drill is perfectly suited for creating accurate starting holes and centerings prior to deep drilling. It is primarily utilized in CNC manufacturing to effectively prevent the lateral deflection of subsequent drills. By matching common point angles, it protects the cutting edges of the following drill, increasing process reliability when working with structural steel, stainless steel, cast iron, and aluminum alloys.

Special features

The HSSCo8 construction provides solid hot hardness and wear resistance, allowing tough materials to be spotted reliably. Thanks to the universal cylindrical shank, the tool is fully compatible with standard chucks and holders. Please note the staggered minimum order quantity depending on the selected diameter to plan your tool requirements efficiently.
