A drill bit, such as a twist drill, having a body equipped with flutes, as well as a drill bit face that includes two main cutting edges that merge together. In order to drill a blind hole, such as with a level drilled bottom, the main cutting edge forms a continuous cutting edge that runs in a plane perpendicular to the drill bit's longitudinal axis. The main cutting edges, with respect to a cutting direction, are arranged behind a center line lying in the plane which is perpendicular to the longitudinal axis of the drill and extending through the center of the drill as well as in the direction of the main cutting edges. |
