Abstract
A device for quickly stopping a medical or dental drilling tool includes a drilling tool having a body extending between a connection end and a working end and having a longitudinal extension along a longitudinal axis of the drilling tool. The drilling tool has a hollow outer shell in which a probe is held that can be moved along the longitudinal axis so that a part of the probe can be moved out of the shell through an opening. The probe is designed as an elongated pin, and its first end facing the connection end is held in the interior of the shell. An electromagnetic sensor for detecting relative movement between the shell and the probe is arranged along the longitudinal extension of the body. The drilling tool has a channel for a treatment fluid extending along the longitudinal axis.
