ABSTRACT:
A cutting tip for automatic milling has the basic form of a parallelogram along whose longitudinal sides (1) straight cutting edges are constructed. Radius cutting edges which are located on the parallelogram transverse edges with the smaller corner angles are attached to it and run into edges which end in the area of the parallelogram transverse sides. In order to also use the transverse sides of the parallelogram type basic form for milling processes, cutting edges are arranged on the parallelogram transverse sides whereby at least one curvature radius (3) is substantially larger then the curvature radius of the radius cutting edges (2). Between these lesser curved cutting edges (3) and the radius cutting edges (2) there is an edge area (4) with a concave curvature.
