Abstract

The milling cutter, in particular a round-head milling cutter, has a tool head, which extends along an axial direction and has a number of cutting teeth that each have a cutting edge. Chip flutes are located between each of the cutting teeth. The cutting teeth each have a front-side radial portion and a circumferential axial portion. The respective cutting edge and the chip flute are disposed such that they are inclined in opposite directions with respect to the axial direction such that the cutting tooth widens towards a foot region. In another embodiment, the tool head has two parts: a carrier part made of a tool steel, and a cutting part made of hard metal fastened to the carrier part. The milling cutter is distinguished by a long service life with a high cutting rate and a high quality of machining.
