Abstract
A method for producing a cutting tool, in particular a drill bit, is specified wherein the cutting tool has a front end (F) at the front and a rear end (R) toward the rear, wherein a tool tip is formed on the front end (F), a point thinning is ground at the tool tip with a grinding tool, the point thinning being ground to be narrower toward the front than toward the rear. The point thinning is ground with a constant point thinning angle (AW). Furthermore, a corresponding cutting tool is specified.

A method for producing a drill bit having a front end (F) and a rear end (R), the front end (F) having a tool tip, the method comprising grinding a point thinning at the tool tip with a grinding tool having an axis of rotation (D),
- wherein, in a single grinding pass, the grinding tool is guided along a straight grinding path (P) in which the grinding tool is initially placed at an angle (W) with respect to the straight grinding path (P), and then reducing the angle (W) as the grinding tool moves in a grinding direction(S) toward the front end of the drill bit until the rotation axis (D) of the grinding tool is orthogonal to the straight grinding path (P).
