Abstract
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.
