It is an object to provide a cutting tool which can perform high-quality, high-efficiency machining of a workpiece such as hardened steel. The cutting tool includes a finishing cutting edgewhich initially cuts into the workpiece, and superfinishing cutting edgesfor finishing the workpiece cut by the finishing cutting edge. The superfinishing cutting edgesproject from the finishing cutting edge by a predetermined amount B in such a direction that the depth of cut of the superfinishing cutting edges increases. Each superfinishing cutting edge includes a burnishing portionhaving a predetermined width L in the feed direction of the tool, and a wiper portion. The superfinishing cutting edgesburnish the finished surface formed by the finishing cutting edge, while removing a affected layer formed by the finishing cutting edge.
