Abstract
In order, in a drill tip (2) which is provided particularly for a modular drilling tool, to generate a ridge (18) with supporting chamfers (26, 28) in a simple way, a non-round grinding method is provided, in which, proceeding from a starting rotary position (30) which corresponds to a cutting corner position, the radius is first reduced and is subsequently increased again to form the supporting chamfer (28). There is therefore no need for a separate grinding step to form the supporting chamfers (26, 28). The supporting chamfers (26, 28) preferably extend parallel to the longitudinal mid-axis (22) in the axial direction (24) and intersect coiled chucking grooves (26).
