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 (delta) therewith, wherein the shoulder angle (delta) is greater than 90 DEG , preferably greater than 100 DEG , that the rake face (23) runs at a radial rake angle (epsilon) 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 (epsilon) is positive.
