<p>The disk (1) has a carrier disk (2) provided with grinding lamellas (3) on a front side, and a hollow cylindrical-shaped passage opening (4) provided at middle of the carrier disk. A threaded insert (5) is inserted into the opening for retaining a drive shaft of a drive machine, where the length of a cylindrical part (51) of the threaded insert lying in the opening is shorter than the length (L2) of the opening. The length of the part is measured such that a cylindrical recess (6) is formed at a rear side of the disk, where the recess retains a disk-shaped section at the drive shaft.</p> |
