A power tool, in particular a hand-held power tool, including a support section for setting down the power tool on a substrate, in particular on a workpiece and/or a guide element. The power tool has a support detection device and is designed to detect, by the support detection device, a first support state, in which the power tool is supported on the substrate by way of at least one first region of the support surface, and/or a second support state, in which the power tool is not resting on the substrate by way of at least the first region, and to determine an operating state of the power tool on the basis of the detected support state.

Electric tool

The invention relates to a tool apparatus () with a drivable tool (), comprising a shaft () which is coupled to the tool (), further comprising one or plural braking bodies () which in particular are arranged distributed around the shaft () in the circumferential direction, wherein the tool apparatus () is adapted to bring the one or plural braking bodies () from a release state into a braking state in the course of a braking procedure, wherein in the braking state the one or the plural braking bodies () are in contact with the shaft and thereby exert a braking force upon the shaft (), so that the shaft () and thereby also the tool () are braked and wherein in the release state the one or the plural braking bodies () are not in contact with the shaft ().

Tool apparatus and method

A power tool with a rotatable tool designed as a saw blade or a milling cutter, including a sensor device for detecting a mechanical quantity, the mechanical quantity having a force, an acceleration, a velocity, a deflection, a deformation and/or a mechanical stress, and the mechanical quantity being dependent on a force emanating from the tool, and a control device communicatively coupled to the sensor device, which control device is adapted to recognize a kickback event based on the detected mechanical quantity, where the control device is adapted to selectively determine a first recognition function or a second recognition function different from the first recognition function based on a function determination information, and to perform the recognition of the kickback event based on the detected mechanical quantity using the determined recognition function.

Power tool, system, and method

A power tool, including a support structure, a pivot bearing arranged on the support structure, a shaft mounted on the support structure via the pivot bearing, a rotatable tool coupled to the shaft, in particular a saw blade, milling cutter or grinding wheel, a strain gauge arrangement for detecting a mechanical quantity which depends on a force emanating from the tool, and a control device which is adapted to recognize an event and/or a state of the power tool according to the detected mechanical quantity. The strain gauge arrangement is arranged on a stationary structure section coupled in a force-transmitting manner to the pivot bearing and is not arranged on the pivot bearing.

Power tool and method

A handheld power tool with a rotatable tool, in which the handheld power tool is a saw blade or milling cutter. The handheld power tool includes a sensor device for detecting a mechanical vector quantity. The mechanical vector quantity includes a force, an acceleration, a velocity, a deflection, a deformation and/or a mechanical stress and the mechanical vector quantity depends on a force emanating from the handheld tool. The handheld power tool also includes a control device which is communicatively coupled to the sensor device and is adapted to recognize an event and/or a state of the power tool according to a direction and/or change of direction of the mechanical vector quantity detected by the sensor device.
