Abstract
A high-speed milling cutter has a tool parent body and one or more plate-shaped cutting inserts with a convex, approximately arc-shaped cutting edge. The insert(s) is/are fastened in an insert seat of the tool parent body. Mating elements with mutual contact surfaces for absorbing the centrifugal forces occurring during use are provided in each case between insert seat and cutting insert. The contact surface of the first mating element is designed in the shape of a circular arc, approximately concentrically to the cutting edge. The contact surface of the second mating element is likewise designed in the shape of a circular arc, approximately concentrically to the cutting edge, or consists of at least two contact zones which lie on an imaginary circular arc, approximately concentrically to the cutting edge, the contact surface or the imaginary circular arc coinciding with the contact surface of the first mating element.
