Claims4
A skiving cutter comprising:
- a base having a circular cross-sectional shape perpendicular to an axis;
- and
- a plurality of cutting edge portions protruding from an outer circumferential surface of the base, formed at intervals in a circumferential direction with respect to the axis, and having a tooth trace extending in a direction inclined with respect to the axis, wherein
- each of the cutting edge portions is segmented into a plurality of segmented cutting edges by cutting edge grooves extending in a direction intersecting the tooth trace,
- each of the segmented cutting edges includes an outer circumferential cutting edge which is an edge farthest away from the base among portions forming the segmented cutting edge, and
- a helix angle which is an angle of the tooth trace with respect to the axis is different according to a position in the axial direction of the plurality of segmented cutting edges constituting the cutting edge portion.
