Abstract
The coupling part, in particular cutting head for a drilling tool for the interchangeable fastening in a coupling receptacle, has a coupling pin which is enclosed by a head support surface, wherein the coupling pin has a plurality of types of functional surfaces, namely stop surfaces for transmitting a torque between the cutting head and the carrier, and clamping surfaces for centering and clamping the cutting head in the coupling receptacle. The coupling pin has an axially front pin region and an adjoining, axially rear pin region, and the clamping surfaces and the stop surfaces are arranged in different pin regions. This decoupling and distribution of the functional surfaces to the various pin regions permits simpler production of the coupling pin and an overall more robust configuration.
