ABSTRACT:
An end milling cutter has a cutter head with a pair of opposed slots extending longitudinally inwardly from the end face and generally radially from the lateral surface to a central cylindrical bore. Each slot forms insert-supporting shoulders which extend from the core to the lateral surface of the head. A triangular cutting insert is received in each slot and is supported on one side by the shoulders. A pressed dimple extending inwardly of the cutter head from the end face, engages and supports a second side of each of the inserts such that the cutting edges thereof are at a prescribed diameter.
