To provide a gear cutting tool capable of supplying a coolant liquid to an optimum position even when cutting edges are reground. The gear cutting tool includes the tool body having a plurality of blades on an outer peripheral surface thereof and a center hole, and a nozzle provided in the center hole of the tool body so that a fixed position in the tool body is adjustable. The nozzle includes a flow channel which allows supplied coolant liquid to flow into the center hole of the tool body, and discharge the coolant liquid toward the plurality of blades.

The invention relates to a skiving tool which is designed as a disposable tool and which includes a first front side, a second front side, a toothing formed on its circumference and having teeth. The front surfaces assigned to the first front side are each delimited by a first cutting edge, as well as a coupling device for coupling the skiving tool to a tool spindle of a skiving machine. In order to enable an extended use in the case of such a skiving tool, the invention provides that the skiving tool has the basic shape of a cylindrical disc, that the front surfaces of the teeth assigned to the second front side are each delimited by a second cutting edge, and that the coupling device for use enables coupling of the skiving tool to the tool spindle such that the cutting edges assigned to its first front side come into engagement with the gear wheel to be processed, and enables coupling of the skiving tool to the tool spindle such that the cutting edges assigned to its second front side come into engagement with the gear wheel to be processed. During use, when the first cutting edges have reached their wear limit, the skiving tool is turned and skiving processing is continued with the same skiving tool until the second cutting edges have also reached their wear limit.

Cutting blade pressure angle changes or corrections in power skiving cutters (20) can be realized without the need tor a tool geometry change. An axial shift (26) of the blade reference point (24) will shift the existing involute on the blade profiles (22, 23) into a different radial location. An accompanying shift (AR) of the reference involute profile (30) by approximately the same amount and in the same direction will re-establish the relationship between work gear and cutter. The resulting work gear geometry has the same radial location of the slots, with the same slot width and the same tooth thickness but with a changed pressure angle.

A tool for machining splines on a workpiece comprises a base, a first tooth extending radially from the base and a second tooth extending radially from the base. The second tooth is spaced circumferentially from the first tooth. The first tooth has a first height, the second tooth has a second height and the second height is less than the first height. The first tooth tapers from the base to the tip of the first tooth, the second tooth tapers from the base to the tip of the second tooth and the first tooth is identical to the second tooth to the second height.
