Abstract
Device for fixing drill bits into the head of air motors for hand-held dentists' tools, of the type incorporating a clip in the rotor inside which the shank of the drill bit is inserted. The fixing clip (6) includes longitudinal slits (7) and is acted on at one of its ends by an elastic means which tends to close the head (10) of the clip (6) on to the drill shank by the cooperation of an inclined surface (11) formed on the head of the clip with a matching inclined surface (12) formed on the inside face of the rotor (2), the head of the air motor being further provided with means which allow the shank of the drill to be released, by compressing said elastic means.
