Abstract
A cutting tool is provided and includes a plurality of cutting inserts located in respective insert pockets. The cutting inserts each include a top cutting plane with at least one cutting edge and a bottom support plane. The top cutting plane includes an engagement portion for mating with a respective engagement portion located in the respective insert pocket. A clamping wedge clamps the cutting insert against the respective insert pocket. A shear resistance created between the engagement portions of the cutting insert and the respective insert pocket during operation of the tool is greater than a centrifugal force created during operation of the cutting tool. In an exemplary embodiment, the engagement portions are shown as a plurality of serrations. The cutting tool is particularly useful in high speed milling operations.
