Handpiece for a medical or cosmetic device comprises a rotating drive (5), a clamping device (2) for a rotating tool (3), and a housing (1) holding the rotating drive and the clamping device. The clamping device has a rotating clamping sleeve (20) provided with an axial bore and containing a collet chuck (30). A front clamping sleeve section (25) has an axial insertion opening (23'') in front of an axial bore (23) for a rotating tool which is externally accessible through a housing opening (17). The clamping sleeve has a dirt-collecting chamber (56) in a clamping sleeve section (26) on the end of the collet chuck facing away from the insertion opening. Preferred Features: The dirt-collecting chamber has a greater diameter than the axial bore.
