A power skiving tool, having a shank extending along a longitudinal axis of the tool and a cutting head arranged at a front end of the shank. The cutting head comprises a plurality of circumferentially arranged teeth, wherein each of these teeth comprises a planar rake face at a front end of the cutting head that faces away from the shank, wherein the rake face is inclined at an angle other than 90° with respect to the longitudinal axis. A transition face is in each case arranged between the rake faces of two adjacent teeth. The transition face is arranged at the front end of the cutting head and adjoins the rake faces of the two adjacent teeth. Surface normals in all points of the transition face form an angle greater than 0° with the rake faces of the two adjacent teeth.

Power skiving tool

A whirling tool for machining a workpiece, having: three or a multiple of three cutting plates, wherein each of the cutting plates comprises at least one cutting edge; a cutting plate holder having a plurality of cutting plate receptacles, wherein each of the cutting plate receptacles is configured to receive one of the cutting plates, wherein the cutting plate receptacles are disposed so as to be distributed in a circumferential direction across the cutting plate holder; and a plurality of fastening elements for releasably fastening the cutting plates in the cutting plate receptacles of the cutting plate holder; wherein the cutting plates comprise at least two different kinds of cutting plates, wherein at least one cutting plate of a first kind, and one cutting plate of a second kind are provided for each group of three cutting plates that are disposed beside one another on the cutting plate holder, wherein the cutting plate of the first kind differs from the cutting plate of the second kind by an overall geometry, by a dimension of the at least one cutting edge, and by a shape of the at least one cutting edge.
