A method for the production of a tool extending in the axial direction, as well as tool tip

摘要

In order in the case of a drill bit (2), which in particular for a modular drilling tool is provided, in a simple way a back (18) with supporting chamfers (26, 28) to generate a non-circular grinding process is provided, in which the radius on the basis of a start-rotating position (30), which corresponds to a the cutting deck position first and then reduced again to the design of the circumferential support groove (28) is increased. In this way, a separate grinding step for the formation of the supporting chamfers (26, 28) can be saved. The supporting chamfers (26, 28) preferably extend parallel to the central longitudinal axis (22) in the axial direction (24) and the cutting of coiled chip grooves (26).
