Patent attributes
A cutting plate for rotating tools includes a major cutting edge connected to a minor cutting edge in a radial extension thereof over a cutting corner. A common face joins a longitudinal side of the major cutting edge and the minor cutting edge, while a major flank or a minor flank joins the other side of the major and minor cutting edges. The flank face form a wedge angle The tool is supported on a boring wall with low friction to enable vibration-free machining. A support land near the minor cutting edge has two interspaced support edges. The support edges have the same radial distance from the tool axis over their entire length. The support edges are oriented parallel to the tool axis and the support land has a flat surface parallel to the tool axis.
