Abstract
This cylindrical cutter for skiving comprises a plurality of cutting edge parts in the circumferential direction by having tooth grooves be formed between circumferentially adjoining cutting edge parts with the tooth grooves being formed into a helical shape twisting in the axial direction. Cutting edge grooves are each formed in the cutting edge parts so as to divide the cutting edge parts into multiple sections in the length direction of the tooth grooves.
