A power tool, in particular a hand-held power tool, includes a tool-holding device that rotates about an output axis. The tool-holding device is configured to hold a tool device on the power tool such that the output axis and a tool rotation axis substantially coincide. The tool-holding device has at least a driver device and a clamping device that is movable relative to the driver device. To transfer a driving force to the tool device, the driver device has at least one torque transfer region that is arranged at a distance from the output axis. The driver device and the clamping device are configured to reach through a cut-out of the tool device, which cut-out extends through the entire material thickness of the tool device, and to clamp the tool device via the clamping device, which is movable substantially in a direction radial to the output axis.

Power tool

A tool device for a hand-held power tool, which can be operated such that the tool device is rotated about an output shaft of a tool-holding device, has at least one connecting device, which is detachably connected to an output shaft of the power tool. The connecting device is fastened to the tool-holding device so that a drive axis of the output shaft and a tool axis of rotation substantially coincide. The connecting device has a cut-out and at least one clamping wing, which at least partly bounds the cut-out in the radial direction of the tool axis of rotation and which is bounded substantially in the direction radial to the tool axis of rotation by a first bounding edge, which lies on a first bounding circle around the tool axis of rotation. The clamping wing extends at least substantially along a plane orthogonal to the tool axis of rotation.

A bearing adapter for a disk-shaped accessory tool which has two sides. The bearing adapter includes a bearing unit configured to reduce a bearing recess of the accessory tool. The bearing unit is configured to adjoin the accessory tool and to enclose a portion of the accessory tool on the two sides when the bearing unit is mounted on the accessory tool.

A machine tool, for example a hand-held belt grinder, is subjected to high frequencies outside a working plane between an abrasive belt and a workpiece. In particular, the machine tool is subject to high frequencies in a free-running region of the belt, of an excitation actuator, in particular by a piezo element.

Machine tool, in particular hand-held machine tool

A guide rail for a hand-held power tool includes at least two rail elements, which are to be joined together to form a common rail and which are held on one another by means of a releasable connecting device. The connecting device includes a joint device, by means of which the individual rails can be pivoted between a folded-together non-functioning position and a functioning position that lies in a common plane.

An auxiliary handle for a motor-driven hand tool has a mounting device which forms an upper region and provides a force-transmitting and/or form-locking connection to a hand tool; a handle forming a lower region, a damping element forming an intermediate region and located at least locally between the mounting device and the handle, the damping element having a damping material with which, during an operation of a hand tool, it dampens vibration transmitted through the mounting device to the handle, the damping element in its damping region acting for damping having at least one reinforcing region that has a lower deformability than a remaining part of the damping region and during deviations of the handle in at least two different directions relative to the mounting device causes differently great elastic counter forces.

Auxiliary handle, and hand power tool provided therewith

The invention is based on an auxiliary handle device, in particular for hand-held power tools, comprising a fastening unit which comprises at least one fastening mechanism. It is proposed that the fastening mechanism is provided in an axial direction of a fastening axis in order to achieve a positive connection.

Auxiliary handle device

A hand-held power tool, in particular an electrical hand-held power tool (), includes a drive motor (), a tool shaft (), and a first overload clutch () for limiting the maximum torque that acts on the tool shaft (). Preferably, the hand-held power tool also includes a second overload clutch ().

A dust catcher has a contact element configured to catch abraded material that is produced by a power tool on a workpiece, and the contact element includes a handgrip element for holding the contact element on the workpiece.

In a hand-guided, motor-driven compass saw machine (), having a housing () that contains a saw blade () that can be moved in the vertical direction by a lifter rod (), and having an oscillation mechanism that has a roller lever (), which is contained in the housing so that it can rotate around a horizontal first axis () and supports a roller () that remains in contact with the saw blade () and rotates around a horizontal second axis (), which oscillation mechanism also has a fork lever () that periodically deflects the roller lever (), an adaptive adjustment of the forward saw progress to the advancing force of the compass saw machine () is achieved by virtue of the fact that the oscillation mechanism produces an oscillation of the saw blade () as a function of the pressure.

The invention relates to an electric power tool having a control and/or regulating device for an electric motor. It is provided that the control and/or regulating device () is assigned an electronic memory element () for at least one operating state of the electric motor ().

The saw blade (,) for an oscillating saw machine has a row of M-shaped twin teeth (,) on its toothed edge (,). Each twin tooth has two tooth tips pointing in opposite directions so as to be effective for sawing in two opposite saw blade motion directions. Each twin tooth is alternately twisted about a central twist axis in one rotation direction or another opposite rotation direction out from the saw blade plane so that the tooth tips of each twisted twin tooth point in opposite directions out from the saw blade plane.
