A control method for a power tool for rotary tools comprises rotating a tool holder continuously about a working axis by a rotary drive. A rotary movement of a handle about the working axis is sensed by a motion sensor. A first angle of rotation of the handle is estimated by a first motion estimator, wherein rotary movements beneath a limit value are discounted. A second angle of rotation of the handle is estimated by a second motion estimator, wherein rotary movements beneath the limit value are taken into account. A measure for reducing the torque output of the rotary drive is activated when the first angle of rotation exceeds a first triggering threshold (A1), and when the second angle of rotation exceeds a second triggering threshold (A2) and at the same time a power output of the rotary drive exceeds a power threshold (L).
