The invention relates to an oscillatory drive having an output shaft that can be driven to perform a rotationally oscillating movement about its longitudinal axis and that comprises a free end, a holding fixture at the free end of the output shaft comprising a contact surface for attachment of a tool, a mounting section on the holding fixture, raised relative to the contact surface, that projects to the outside in the direction of the longitudinal axis and that is designed for form-locking connection with a mounting opening of a tool placed in contact with the contact surface, and having a securement for fixing the tool with its mounting opening on the holding fixture, the securement permitting the tool to yield in axial direction under the action of a torque, against a pre-stress, and the mounting section permitting the tool to rotate by a certain angle of rotation when the tool gives way axially.
