A core drill bitincludes a tubular shaft, a mounting platformprovided on a proximal end of the tubular shaftfor mounting the core drill bit on a power tool, and an annular cutting sectionprovided with abrasive cutting segmentsarranged at a distal end of the tubular shaft. A first transponderis provided at the distal end of the tubular shaft. A repeateris provided comprising a second transponderat the proximal end of the tubular shaft, an antennafacing the first transponder, and a wired connectionbetween the antennaand the repeater

The core drill bitfurther includes a transponderand a slitin the tubular shaft. The slitforms a slit antennafor the transponder

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