ABSTRACT:
In a milling cutter, particularly a planer face-milling cutter having at least one blade arranged in a groove of the cylindrical milling cutter body, which blade has a spiral shaped cutting edge, both the sides of the groove which runs at an angle greater than zero degrees relative to the longitudinal axis of the milling cutter body and the side surfaces of the blade to be secured in the groove are planar parallel surfaces. The edge forming the cutting edge of the blade is bulged over the entire length of the blade to provide a uniform spacing above the outer peripheral surface of the milling cutter body. The spiral shape of the cutting edge of the blade is formed by a corresponding ground surface on the edge zone of the blade forming the cutting edge.
