Abstract: A hand guided electrical tool is formed of a housing (1) and a guide part (2) for mounting a drive shaft (3) in addition to a handle (6a) and further an auxiliary handle (5) that can be secured by a locking ring (4) for precise guidance. To assure simple adjustment by the user, the locking ring (4) runs in the axial direction of the drive shaft (3). Furthermore, the auxiliary handle (5) is designed spade-shaped and pivotable around an axis of rotation parallel to the drive shaft (3) and can be secured or locked in different positions. The inside diameter of the locking ring (4) can be changed by means of an actuator element (8).

Abstract: A braking device for an electrical tool and including an actuation member (1), a braking drum (4) secured on the shaft of the electrical tool for joint rotation therewith, and a braking member (5) secured on the actuation member for joint displacement therewith, the actuation member being linearly displaceable upon a biasing force of a return spring acting thereon for pressing the braking member against a circumferential surface of the braking drum for braking the shaft and thereby the working tool.

Abstract: A compass saw comprising a motor-driven reciprocating rod (1) with a tool receptacle (2) disposed at its free end for receiving the clamping shaft (6) of a saw blade (3), a receiving hole (7) and a center bolt (19) that is pre-stressed towards the receiving hole (7), being guided transversely to the reciprocating rod (1) and displaceable in a longitudinal direction (L). The center bolt (19) comprises a centering means configured as a flat bearing surface (21). The bearing surface (21) cuts the longitudinal axis (A) of the reciprocating rod (1) into a slant angle (&agr;).
