Abstract

The invention relates to a drill (1) for medical applications, in particular for drilling in bone, comprising a first end (11) and a second end (12), a cutting area (2) arranged at the first end (11) with cutting edges such as main cutting edges (3) and secondary cutting edges (4), a shank area (5) downstream of the cutting area (2) with a drill bit (6) arranged between the cutting area (2) and the second end (12), wherein the drill bit (6) is wider relative to the cutting area (2). According to the invention, to facilitate the detection of the drill bit (6) contacting an object such as a bone screw, at least one external thread (8, 9) is arranged in the shank area (5) between an end face (7) of the drill bit (6) and the second end (12).
