Abstract (en)

The invention refers to a hand held or hand guided grinding or polishing machine tool (1), the tool (1) comprising: - a working element holder (12) having a first connection element (36) for connecting the working element holder (12) to a disk-like working element (9) and a center axis (14), - the first connection element (36) for connecting the working element holder (12) to the working element (9) having a rotational axis (37) running parallel to the working element holder's (12) center axis (14), - the working element holder (12) further having a second connection element (15) for connecting the working element holder (12) to a motor shaft (22) of the grinding or polishing machine tool (1) in a torque proof manner, and - the second connection element (15) for connecting the working element holder (12) to the motor shaft (22) having a longitudinal axis (16) running parallel to the first connection element's (36) rotational axis (37) and to the working element holder's (12) center axis (14). In order to provide for a larger orbit of the working element (9) and to reduce vibrations of the tool (1) it is suggested that all three axes (14, 16, 37) are spaced apart from one another by predefined distances.
