In a dental handpiece with an elastically arranged reception part (8) for a tool, compressed air from angled exit nozzles (9) can be applied to a sleeve (7) allocated to the reception part (8) with radial play. The circulating movement of the sleeve (7) is converted into a vibration of the reception part (8), the plane of vibration lying essentially perpendicular to the longitudinal axis of the reception part (8).
