COUPLING POINT FOR A MODULAR ROTARY TOOL AND TOOL HEAD CARRIER FOR A MODULAR ROTARY TOOL

摘要

A coupling point for a modular rotary which extends in an axial direction. The coupling point includes a first coupling part disposed on a tool head and a second coupling part disposed on a carrier. The coupling parts can be coupled to one another by bidirectional rotation with the formation of an interference fit which acts in the radial direction. Each coupling part includes two coupling faces which lie opposite one another and have contact regions in which the interference fit is formed. In the first coupling part, at least one of the coupling faces has at least two contact regions which are spaced apart from one another in the circumferential direction, and, to this end, at least one first clearance portion is formed between the contact regions, in which clearance portion the two coupling parts do not bear against one another in the coupled state.
