摘要： A twist drill including a cutting tip having a front flank face, a substantially cylindrical tool body extending rearwardly from the cutting tip, and a shank. The tool body includes a rotational axis therethrough and at least one flute formed on an outer peripheral surface thereof and extending to the front flank face. The at least one flute includes a first helical portion opening to the front flank face and a second helical portion extending from the rear end of the first helical portion toward the rear portion of the tool body. The second helical portion twists in a direction opposite of the first helical portion.

摘要： 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.
