The invention relates to a screwing tool comprising a drive arm (1) that has a handle section (2) and that carries a gear head (3) having two broad side planes (10, 11) facing away from each other at the end of the drive arm, wherein a freewheel lock (4) is arranged in the gear head (3), comprising a polygonal opening (20) that can be rotated incrementally about the rotational axis (9) of the freewheel lock (4) by moving the drive arm (1) back and forth about the rotational axis (9) and that is used for inserting an output polygon (8), wherein the screwing tool can also be used as a hammer, for which purpose the gear head (3) comprises at least one impact surface (6). The output polygon (8) is inserted in the polygonal opening (20) so as to be movable back and forth in the direction of the rotational axis (9) between two detent-secured screwing positions, wherein in the screwing positions the output polygon (8) forms an output part protruding from one of the two broad side planes (10, 11) in each case, wherein the impact surface (6) forms two sections (13, 14) projecting over one of the two broad sides (10, 11) in each case and the output polygon (8), in a middle position lying between the screwing positions, projects approximately equally far above the broad side surfaces (10, 11) on both sides.

The invention relates to a chuck for receiving tools (1) that are operated by rotating around the axis thereof, particularly screwdriver bits, comprising an insertion section (3) which is provided with a seat cavity (2) having a non-circular cross-sectional area (3). The tool can be locked in said seat cavity (2) by means of a holding element (4) which is assigned to the cavity wall in order to prevent the tool from being withdrawn from the seat cavity (2). The holding element (4) can be deactivated by displacing an actuating member, particularly in the form of an actuating sleeve (5). The tool (1) rests backwards against the seat cavity (2). According to the invention, the tool (1) can be displaced from the resting position in the direction of the opening of the seat cavity (2) by actuating the actuating sleeve (5). In order to facilitate removal of the bit, the inventive chuck also comprises means (15, 16, 17) for releasing the face (1') of the bit and a magnet (9) which retains the bit in the cavity from the resting position.

The invention relates to a device for storing a number (an assortment) of essentially similar screw tools (3) of different sizes. The device has an opening (2) allocated to each screw tool (3). In order to make the inventive storage device (1, 1', 1'') more advantageous to use, it also forms a magnetising/demagnetising device (5, 5').

The invention relates to a screwdriving tool, comprising a gear head (205) and a drive arm (203). The gear head (205) forms a gear housing (212), in which a free wheel or ratchet gear (202) having an output rotational axis (201) is arranged. A front side of the gear head (205) comprises an output coupling (204), particularly in the shape of a polygon. The drive arm (203) can be pivoted about a pivot axis (208), which is substantially transverse to the output rotational axis (201), from a quick-action screwdriver position, in which the drive arm (203) is in the output rotational axis (201), into a power-action screwdriver position, in which the drive arm (203) extends substantially transversely to the output rotational axis (201) and can be fixed in both pivot positions by detent means (206). The detent means (206) can be moved from a detent position into a release position by means of an actuating member (213) associated with the drive arm (203). For an enhancement that is advantageous for use, it is proposed to provide two centrifugal masses (225), which are arranged diametrically opposed from each other and associated with the drive arm (203), and a sleeve (226) that is rotatably associated with the drive arm (203).

The invention relates to a device for profiling toothed workpieces, in particular for the generation of undercuts or similar on geartooth flanks of internally or externally toothed working gears. The above is achieved by machining of the rotationally driven workpiece, using a rotationally driven cutting edge tool (1), the cutting edge (3, 5) of which intermeshes with the gearing of the workpiece. The cutting edge (3, 5) of the cutting edge tool (1) which is rotated in a worktool axis, parallel to the workpiece axis, with a fixed speed relative to the workpiece, is displaced on a curve (19) corresponding to the profile shape in accordance with a combination of the variation of the distance between axes and the variation of the phase position or the inclination of the axis position superimposed to the rotational movement, whereby the direction of cutting extends toward the tooth base. The invention is characterized in that the cycloid trajectory of the cutting edge (3, 5) defined by the distance between axes (AS, AZ), the orbit (F) of the cutting edge (3, 5) and the gear ratio is selected in such a manner that the advance branch (21') of the cycloid loop intersects (21''') with the return branch (21'') of the same cycloid loop.

The invention relates to a storage device comprising a storage container (1, 2) that can be brought from a storage position in which a tool stored therein (3) cannot be removed, to a removal position, in which the tool stored therein can be removed, with an indication element (4) indicating the tool (3), said indication element being distinct from the storage container (1, 2) but firmly attached to the storage container (1, 2) and visible in the storage position. According to the invention, an indication element (4) is provided that can be attached to the storage container in simple manner and is not only visible but also palpable, wherein the indication element (4) is a flattened relief of the tool (3).
