  • Patent number: 8403341
    Abstract: An adapter is provided for a motor-driven machine tool which includes a tool driven in an oscillating rotational pendulum motion. The machine tool includes a driveable tool shaft (1), the end face of which is designed as a locating flange (2) having at least one form-fit element (3) for receiving and fastening the tool (5). The adapter (9) includes, on an end face (16), form-fit counter elements (10) which are matched to the form-fit elements (3) of the tool shaft (1). A plurality of axially projecting mandrels (11) is distributed around the circumference on the opposite end face (13) of the adapter (9).
    Type: Grant
