ABSTRACT:
A milling tool includes a supporting body that is rotatable around a central axis, and is being equipped with detachable cutting inserts. Each insert has two cutting edges extending at a given setting angle relative to each other. One of the cutting edges is located in a reference plane oriented perpendicular to the axis of rotation. In order to directly or indirectly connect each cutting insert with the supporting body a pair of serrated surfaces are provided, each of the serrated surfaces consisting of oblong, parallel ridges that are separated by grooves. A first one of the serrated surfaces is located at an inner side of the cutting insert, and the other one being directly or indirectly associated with the supporting body. The ridges and the grooves of the serrated surfaces are relative to the reference plane by an angle that constitutes one-half of the setting angle.
