ABSTRACT:
A ball nose end cutting tool having cutting bit inserts which may be quickly and accurately positioned on a tool holder and secured thereto with ease. The present construction permits the cutting bits to be mounted in a substantially end-to-end relationship for cutting to the center of the tool holder thereby reducing the cutting forces at the center. The tool holder has a pair of opposed bit-receiving pockets formed therein that are adapted to hold two identical high-speed cutting bits. Each pocket includes a dovetailed locator edge surface, a planar inner side wall, and an open outside area which permits unrestricted chip flow. The cutting bits are adapted to seat against the dovetailed locator edge surfaces and planar side walls of the two pockets in the tool holder. The planar side walls are oppositely inclined, each being at an approximately 5.degree. negative rake angle to the longitudinal axis of the tool holder, for the purpose of properly positioning the cutting edges of the bits. The cutting edges are positioned to provide a cutting action from the outside periphery of the tool holder inwardly to the center of the holder. In plan view, the cutting edges form a substantially continuous trigonometric reverse curve from the center of the holder with the curve having substantially parallel outwardly extending tangent portions.
