ABSTRACT:
A rotary cutter head is provided with helical carbide cutting blade inserts. The blade inserts extend along a helical path and are configured for cutting rotation in a predetermined direction. The blade inserts are secured to the cutter head body in a helical slot formed between a wall of the cutter head body and a plurality of clamping wedges. The blade insert may have a tapered body that facilitates locking and securing the blade insert to the cutter head body in a radial direction in response to centrifugal forces created as the rotary cutter head rotates.
