Abstract: A tool for working a substrate has a stator and a working piston, which is intended to move relative to the stator along a working axis and toward the substrate or to hit a fastening element, in order to drive the fastening element into the substrate, also having a drive, which is intended to drive the working piston along the working axis onto the substrate, the drive having a piston coil capacitor and a piston coil arranged on the working piston, the piston coil being electrically connectable to the piston coil capacitor in order during rapid discharge of the piston coil capacitor to have a current flowing through it and to generate a magnetic field which accelerates the working piston relative to the stator.

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 tool for working a substrate, having a stator and a working piston, which is intended to move relative to the stator along a working axis, and having a drive, which is intended to drive the working piston along the working axis from a starting position onto the substrate, the drive having a stator coil arranged on the stator and being intended to apply electrical current of a first current intensity I1 to the stator coil in order to generate a magnetic field which accelerates the working piston relative to the stator, the drive having a piston coil arranged on the working piston and being intended to apply electrical current of a second current intensity I2 to the piston coil in order to generate a magnetic field which accelerates the working piston relative to the stator, the second current intensity I2 being less than the first current intensity I1.

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.
