  • Patent number: 10124421
    Abstract: An end milling cutter for heat-resistant superalloys (HRSA) has a shank and a cutting head, which have a common rotation axis, the shank having a connection section for connection to the cutting head and a coupling section for connection to a tool holder, the cutting head consisting of a solid ceramic part, which has a rotationally symmetrical envelope and is butt-joined to an end face of the connection section. In order to keep excessive vibrations and thus stresses low in the interface between the cutting head and the connection section of the milling cutter and to create milling cutters that can also cover the diameter range above 12 mm and in particular above 20 mm and up to 32 mm, the coupling section has a conical peg having an external thread.
