Abstract

The drill, comprising a shank (1) and a tip (2) with at least two main cutting edges (3) and helical chip grooves (4), is provided with a hard-material coating. In addition to the main and auxiliary cutting edges and the rake surfaces (5), this coating also covers the chip grooves, but is limited to a drill tip zone (B) of length (l) equal to at most three times the drill diameter (D). Also claimed is the method for producing such a drill, comprising finish machining the drill without coating, after which it is coated in a sputter installation with use of a sleeve covering the drill with the exception of a drill tip zone of length equal to at most three times the drill diameter.
