摘要：
A rotary cutting tool, such as a milling cutter (10) includes a central hub (12), a cutting rim (14) and a plurality of spokes (22) connecting the central hub (12) to the cutting rim (14). Each spoke (22) is separated by an opening (32) and polygonal in cross-sectional shape formed by two side walls (22a, 22b), two front walls (22c, 22d) and a rear wall (22e). One of the side walls (22a) of each spoke (22) is formed at a pitch angle (42) with respect to a central axis (11) of the cutting tool (10) that is sufficient to cause lift of chips through the opening (32), thereby providing effective chip evacuation during a material removal operation.
