Cutting head, rotary tool and support for the rotary tool and for the accommodation of the cutting head

摘要

A cutting head is formed for insertion into a support in a modular rotary tool, in particular a drill. The coupling head has a coupling having torque surfaces and clamping surfaces on its outer periphery. The coupling pin is divided into a front pin part and a rear pin part. The front pin part is defined by a circumferential groove. Stop surfaces for an axial pullout safety are formed in the transition area between the two the front pin part and the rear pin part. The torque surfaces and the clamping surfaces are arranged in different pin parts. For example, the clamping surfaces are preferably formed on the front pin part and the torque surfaces are preferably formed in the rear pin part.
