摘要： 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.
