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