ABSTRACT:
In a cutting element for cutting metals and having adjacent surfaces which meet to form a cutting edge, with a chip-controlling groove being formed in one of the surfaces, the groove being composed of a plurality of depressions disposed parallel to one another, spaced apart in the direction of the groove width, and extending along substantially the entire cutting edge, the ability of the groove to effectively deflect chips having a wide range of thicknesses, or cross sections, is improved by forming the groove to have more than two such depressions, with the depressions arranged to form a ridge between each two adjacent depressions, the ridges being located such that, in the direction extending away from the cutting edge, each succeeding ridge is at a higher elevation than the preceding ridges.
