Abstract
An insert for milling applications in which a radial rake face includes a concave conical portion defined to achieve constant positive radial rake throughout the length of a radial cutting edge at the angle of inclination thereof as the insert is intended to be mounted in a cutter body. The insert includes an axial rake face having a sloping portion defined to achieve positive axial rake as the insert is intended to be mounted in a cutter body. The upper surface of the insert includes planar regions and bend surfaces merging smoothly with the radial rake faces and axial rake faces to assist in chip expulsion during cutting.
