The invention concerns a dental drill system (1), comprising a drill (2) having a drilling part (3) with a first end (4) configured for drilling a hole in a jaw bone and a shank part (5) with a second end (6) configured for connection to a drill-rotating device and a guiding sleeve (7) for guiding the drill (2) during drilling, wherein the guiding sleeve (7) has a first side (8) intended to face the drill-rotating device and a second side (9) intended to face the jaw bone during a drilling operation, and wherein a guiding through-hole (10) extends from the first side (8) to the second side (9). The invention is characterized in that a rim (11) extends at least partly around the circumference of the drill (2), and in that the system (1) comprises a drill stop sleeve (12, 121) that is capable of being brought onto the drill wherein the drill stop sleeve (12) is provided with a recess (13) extending circumferentially around an inner side of the drill stop sleeve (12, 121), wherein the relative dimensions of the rim (11) and the recess (13) are adapted to allow the drill stop sleeve (12, 121) to be snap-locked onto the drill (2), and wherein the guiding sleeve (7) comprises a flange (14) that defines an end position for the drill stop sleeve (12, 121). |
