Abstract

A drill tip (2), a drill shank (3) as well as a drive section which can be inserted into a location opening of a drive part are provided on a drill (1). The drive section has a head (4) which is enlarged relative to the drill shank (3) and has at least one flat (16), running parallel to the drill axis, for the rotary driving in a drive part. The shank section (21) of the drill (1) directly following the head (4) is embodied in a drive part in order to align the axis of the drill (1) accurately. The ends (14, 15) of the head (4) remote from each other in the axial direction are designed as stop surfaces for axially limiting the movement of the drill (1) in a location opening of a drive part. <IMAGE>
