ABSTRACT:
An end milling tool has a main body formed at its front end with a long main cutting end edge extending generally radially from the outer periphery of the main body approximately to the center of the main body and with a short auxiliary cutting end edge extending from a different location on the outer periphery generally radially inwardly to a position spaced from the center. An outer peripheral cutting edge is formed at an outer peripheral portion of the main body and is continuous with each of the main and auxiliary cutting edges. The main cutting end edge projects axially of the main body beyond the auxiliary cutting end edge to prevent the auxiliary cutting end edge from breaking or chipping.
