Tool

摘要

Tool comprises a support part (1), a disk-shaped working part (2) for machining, and a common axis (6). The support part has a bearing surface (5) with at least one permanent magnet (14) for the working part. The working part has a counter-bearing surface (15) for the bearing surface. When the counter-bearing surface is placed on the bearing surface, a ferromagnetic coupling part (19) of the working part is connected in a magnetic manner to the permanent magnet. Preferred Features: The permanent magnet is arranged in a recess (11) in the support part. The coupling part is inserted into the recess.
