Abstract: In order to provide a handheld abrading machine which is of robust construction and is easy and comfortable to handle, it is proposed that the handheld abrading machine comprise a holding device for holding the abrading machine, a drive motor and a tool head, wherein the tool head is arranged on the holding device such as to be moveable by means of a moving device, wherein the tool head is pivotal relative to the holding device about one or more pivotal axes by means of the moving device and wherein a distance of the tool head from the holding device is variable by means of the moving device.

Abstract: In order to provide a handheld abrading machine which has a simple, efficient and as fatigue-free an abrading action as possible and which includes a holding device for holding the abrading machine, a drive motor and a tool head, wherein the holding device includes a substantially tubular bar that has a proximal end and a distal end, wherein the drive motor is arranged at the proximal end, wherein the tool head is arranged at the distal end, wherein the abrading machine includes a transmission shaft which connects the drive motor to a tool holder of the tool head for transmitting torque thereto and which runs at least in sections thereof within the tubular bar, it is proposed that a motor shaft rotational axis of the drive motor be oriented transversely, and in particular inclined, relative to a longitudinal axis of the tubular bar.

Abstract: In order to provide a tool holder for holding a tool for treating the surface of a workpiece by means of which it is possible to treat workpieces in a low-vibratory and convenient manner, it is proposed that the tool holder comprise a disk-shaped base body which has an attachment section for the attachment of the tool holder to a machine tool and at least one resiliently flexible deformation section.

Abstract: A handheld abrading machine is provided, including a holding device which includes a substantially tubular bar having a proximal end and a distal end and having a drive motor arranged at the proximal end and a tool head arranged at the distal end, and a transmission shaft connecting the drive motor to a tool holder of the tool head and running within at least sections of the tubular bar. The tool head includes a hood device which includes a hood element having a substantially cylindrical hood chamber, wherein the tool holder together with a tool arranged thereon is arrangeable in at least sections of the hood chamber. The hood element includes a recess in the form of a segment of a cylinder so that a tangent touching an edge of the tool runs substantially in a plane delimiting the recess in the form of a segment of a cylinder.

Abstract: In order to provide a hand-held cleaning/polishing machine, comprising a holding device for holding the cleaning/polishing machine, a drive motor, a tool head for one or more cleaning tools and/or polishing tools, which has a tool drive shaft driven by the drive motor, and a transmission device for transmitting torque from the drive motor to the tool drive shaft, which is universally usable, it is provided that at least one coupling for connecting at least one first fluid line is arranged on the holding device and that at least one second fluid line leads to the tool head from the at least one coupling.

Abstract: In order that a hand-held machine tool for introducing cuts, comprising a drive motor for at least one cutting tool and a contacting device, by which the hand-held machine tool is adapted to contact an object to be machined and is guidable on said object, may be provided that is universally usable, it is proposed that the drive motor is disposed in a lockable pivotable manner relative to the contacting device, wherein at least one pulling position for the pulling introduction of a cut and at least one pushing position for the pushing introduction of a cut is adjustable.

Abstract: In order to provide a hand machine tool comprising an elongated housing, a drive motor which is arranged in the housing and with which a tool holder can be driven via a miter gear, a first handle unit arranged on a housing section located close to the tool holder and aligned transversely to a longitudinal axis of the housing and a second handle unit arranged on the housing, with which the alignment of the first handle unit relative to the axis of rotation of the tool holder may be varied, it is suggested that the first handle unit be held for guidance in an adjusting guide means on the housing and in this adjusting guide means be adjustable within an angular range of at least 90° about a longitudinal axis of the housing between several possible positions and be fixable in a positive-locking manner in the respective position.

Abstract: A releasable coupling for motorized machine tools including first and second coupling elements which are uncoupled when a predetermined triggering torque occurs. The first coupling element includes first locking elements, such as balls, while the second coupling element includes corresponding second locking elements, such as recesses. The first coupling element includes a concentric holding element. The holding element is rotatable with respect to the first and second coupling element between an inactive position and an active position. In the inactive position, the holding element allows the first and second locking elements to engage one another to maintain the first and second coupling elements in a coupled arrangement. After the predetermined triggering torque has occurred and the holding element is rotated into the active position, the holding element prevents the first and second locking elements from engaging one another to maintain the first and second coupling elements in a uncoupled arrangement.
