摘要： To provide a highly practical rotary cutting tool with which chips can be satisfactorily removed even during longitudinal feeding, and the accumulation of chips can be minimized. A rotary cutting tool is provided, wherein a large number of helical chip-removing grooves (2) are provided in an external periphery of a distal end of a substantially cylindrical tool main body (1), and end cutting edges are provided at the lines of intersection between the cutting faces (3) of the chip-removing grooves (2) and the distal-end flanks of the tool main body (1); and at least one of the end cutting edges is configured so that the part of the cutting edge near the external periphery of the tool is recessed in the axial direction of the tool main body (1), forming a non-cutting part (22).
