A milling tool has a cutting edge geometry with a main cutting edge, a cutting corner, optionally with a bordering planar cutting edge segment, and a secondary cutting edge. The tool is used for milling to achieve the smoothest level surface possible parallel to the rotational axis of the milling tool. Each main cutting edge is formed to result in a generatrix of the envelope curve described by the rotation of the milling tool that has a first outwardly curving segment and a second inwardly curving segment. The first segment increases in its distance from the rotational axis from the beginning of the segment to the end of the segment. The distance of the second segment decreases from its beginning towards its end. The tangents at each point of the second segment encompass an angle &#x3b1;of more than 0&#xb0; and up to 3&#xb0; with a parallel to the rotational axis.

A cutting tool for high-speed machining has at least one cutting insert that is interchangeably mounted to a main body of the tool. At least parts of the supporting surface of the cutting insert and of the receiving surface of the main body of the tool, when viewed in cross section perpendicular to the axis of rotation, are of an approximately V-shaped configuration and are engaged with each other. The crown region and also at least one of the end regions of the V-shaped supporting surface and receiving surface are mutually relieved. A bearing surface on the main body of the tool, in order to radially support the cutting insert, is arranged in such a way that a mounted cutting insert is tilted such that the supporting surface of the main body and the receiving surface come into mutual contact at only two points.
