ABSTRACT:
A replaceable on-edge cutting insert is especially adapted for use in end-milling cutters of small diameter, viz., in the size range down to one-half inch in diameter, and with cutting geometry which positions the rake face of the insert in the cutter body with substantially neutral radial rake and positive axial rake. A modified form having a cylindrical primary clearance land is used in the tip cutting positions of a ballnose end mill.
