ABSTRACT:
A rotary cutting tool has a plurality of helical channels located in the body of the rotary cutting tool. Individual cutter segments are bonded within each helical channel to form a continuous helical cutting edge that is machined to a finished state. An area of the tool body adjacent to the helical channel is removed to create helical flutes. Preferably, the segments are cut from disks of polycrystalline diamond (PCD) or polycrystalline cubic boron nitride (PCBN).
