ABSTRACT:
A disk-shaped tool bit (8) of an angle grinder has an annular disk-shaped carrier member covered on its radially outer circumferentially extending surface and on its side face surfaces with abrasive grains. A central through opening extending between the side face surfaces (8a, 8b) serves for attaching the tool bit to the angle grinder. The central through opening has a surface extending between the side face surfaces and tapering inwardly from each side face surface toward the axis of the central opening. The inwardly tapering surfaces form engagement surfaces (8c, 8d), at which an attachment element (11) of a receiving device (7) of the angle grinder bears for securing the tool bit in place. The attachment element (11) does not project outwardly from the side face surface (8b) facing outwardly from the angle grinder.
