Abstract: A milling insert, including an upperside, an underside, and a reference plane parallel to the upperside and the underside. A plurality of indexable cutting edges are formed along a peripheral borderline in transitions between at least the upperside and a number of clearance surfaces. Each cutting edge includes a chip-removing main edge and a surface-wiping secondary edge, the secondary edge forming an obtuse angle with the main edge as viewed in planar view from the upperside. The main edge, from a first end of the main edge adjacent to the secondary edge, first declines toward the underside of the milling insert and then, from a lowest part, rises toward an opposite second end of the main edge. The secondary edge is inclined at an angle (?) in relation to the reference plane as viewed perpendicularly to the clearance surface of the secondary edge, such that a first end of the secondary edge connected to the main edge is situated on a lower level than the opposite, second end of the secondary edge.

Abstract: The invention relates to a milling tool for gear milling. The tool body is equipped with tangentially mounted milling inserts having four cutting edges and two holes, only one of which is utilized for a fixing screw in two of totally four index positions. By locating a screw hole in the seat of the milling insert at a distance from the radial support surface of the seat that is greater than the distance between an individual hole and a distal end of the milling insert, a clamping force is provided by means of the inherent elasticity of the fixing screw. In such a way, the milling insert is pressed against the radial support surface. By means of a transversal eccentricity, the milling insert is also pressed against a tangential support surface in the seat. By means of this construction, the two holes in differently long milling inserts can be formed with equally large distances from distal ends. Thereby, one and the same tool body can be equipped with differently long milling inserts.
