Abstract: A control method for a power tool for rotary tools provides the following: A tool holder is rotated continuously in a forward direction about a working axis by a rotary drive when an operating switch is actuated. The continuous rotation in the forward direction is interrupted by a protective process when a protective device senses blocking of the tool holder. During the protective process, one or more cycles are executed, in which the rotary drive is actuated successively in accordance with an unimpeded rotary movement in a reverse direction and in accordance with an unimpeded rotary movement in the forward direction. The rotary drive is supplied with a first amount of energy for the rotary movement in the reverse direction and with a second amount of energy for the rotary movement in the forward direction. The first amount of energy is smaller than the second amount of energy.

Abstract: A core drill bit 1 includes a tubular shaft 12, a mounting platform 34 provided on a proximal end of the tubular shaft 12 for mounting the core drill bit on a power tool 35, and an annular cutting section 2 provided with abrasive cutting segments 3 arranged at a distal end of the tubular shaft 12. The core drill bit 1 further includes a transponder 24 and a slit 27 in the tubular shaft 12. The slit 27 forms a slit antenna 26 for the transponder 24.

Abstract: A sensor arrangement includes a sensor collar where the sensor collar has a sensor sleeve for insertion into an anchor hole and has a sensor flange which is fixedly connected to the sensor sleeve and which radially protrudes from the sensor sleeve for abutting on a mouth of the anchor hole. A through hole extends through the sensor sleeve and through the sensor flange. The sensor arrangement further includes a sensor where a physical quantity of the sensor flange is determinable by the sensor.

Abstract: A power tool having a tool and a motor, with the motor of the power tool being operated in a speed range from 2,000 to 30,000 rpm and with an inertia of the motor lying in a range from 20·10−6 to 750·10−6 kg·m2. In a second aspect, the invention relates to a method for operating a power tool which is operated in a speed range from 2,000 to 30,000 rpm, with an inertia of the motor lying in a range from 20·10−6 to 750·10−6 kg·m2. By selecting and specifying a set of parameters which describe characteristics of the motor of the power tool, the power tool can be designed and operated in such a way that a mechanical slip clutch can be dispensed with. The motor parameters “speed” and “inertia” are selected in particular so that a maximum torque in a transmission of the power tool is always below a specified upper limit.

Abstract: A control method is provided for a hand-held power tool (1), which includes a motor (5) for rotationally driving a tool holder (2) about a working axis (12), including the following steps: detecting a rotary motion of the hand-held power tool (1) about the working axis (12); detecting a rotary or pivoting motion about a transverse axis (18) extending transversely to the working axis (12); triggering a safety function for reducing the torque output of the motor (5) when the rotary motion about the working axis (12) exceeds a limiting value, and suppressing the safety function when the rotary or pivoting motion about the transverse axis (18) is greater than a threshold value.
