A drilling tool for producing drill holes includes a tip and a shaft arranged opposite the tip in a direction of a longitudinal axis of the drilling tool. The drilling tool has at least one geometrically defined cutting edge in the tip area, and has an expanded diameter trailing the tip in a longitudinal direction from the tip. The drilling tool has a first area with a first diameter that precedes the expanded diameter, and a second area with a second diameter, larger than the first diameter, that trails the expanded diameter. The drilling tool is distinguished in that the expanded diameter and/or the second area is/are embodied such that chips are produced in the area of the expanded diameter and/or in the second area when a workpiece is machined, chips consistent with those produced when a workpiece is machined with a geometrically undefined cutting edge.

Abstract

What is proposed is a drill (1) having a tool shank (3), a central axis (5) and a first cutting region (7) with at least one geometrically defined first lip (9; 9'), which has a rake face (23) and is arranged at a radial distance from the central axis (5) of the drill (1), wherein the first lip includes a countersink angle (a) with the central axis. The drill (1) is distinguished by the fact that the first lip (9; 9') is assigned a chip breaker, which is formed by the rake face (23) of the first lip (9; 9') and by a shoulder face (31) which adjoins the rake face (23) and includes a shoulder angle (δ) therewith, wherein the shoulder angle (δ) is greater than 90°, preferably greater than 100°, that the rake face (23) runs at a radial rake angle (ε) with respect to an imaginary radial line (L) which intersects the first lip (9') assigned to the rake face (23), and that the radial rake angle (ε) is positive.
