The motor handpiece (4) has a housing (14), in which a receiving space (26) is provided between a terminal end (18) and a working end (22). An electric motor (28) is accommodated in the receiving space for driving a tool (30) attached at the working end. A cooling path (34) for guiding a cooling medium is arranged adjacent to the receiving space. The cooling path is integrated into the housing by forming a material recess in a single-piece housing wall (16). The cooling path has multiple cooling sections around the receiving space. |
