ABSTRACT:
A ball end mill has a cylindrical tip embedded at the revolving center of the end of the cutter body in the axial direction and one or more arc-shaped flat tips embedded at the end of the cutter body in the radial direction, the former serving as a cutting edge for milling the central part and the latter serving as a cutter edge for milling the peripheral part. Both cutting edges perform uniform milling action and exhibit outstanding durability. The use of throwaway tips extends the life of the tool.
