摘要：
Various medical or dental handpieces having at least one coil for inductive coupling with a second coil and methods for using these handpieces for the transmission of at least one of power, operational data and identification data are described. Also various tool-holding/releasing devices for medical or dental handpieces are described, having at least one shaped element penetrating through a bore in a hollow shaft for accommodating a tool and protruding through the bore into the hollow shaft, a movably arranged locking sleeve cooperating with the shaped element and an operating element for moving the locking sleeve. Some of these tool-holding/releasing devices allow the insertion of the tool into the hollow shaft with different insertion depths.
