A dental handpiece, which has a drive motor part with a drive shaft for rotation in a housing, and a grip section connected to the housing and having a head part with a socket for receiving and mounting a tool for rotation, and a drive train coupled to the drive shaft to transfer rotary motion from the motor to the socket, characterized by a sleeve surrounding the housing and being axially removeable from the housing and the grip section so that parts of the handpiece can be individually sterilized as necessary without subjecting the motor to sterilization.
