1. A cutting tool for the rotary machining of workpieces comprising:
a cutting tip which has at least one main cutting edge and at least one free surface, wherein a flank face adjoins the main cutting edge radially outward from the main cutting edge and adjoins a guide bevel located on a peripheral surface of the cutting tool, wherein the main cutting edge merges into an edge of the flank face, and wherein a flank angle of the flank face, measured in a section perpendicular to the main cutting edge, continuously increases from the main cutting edge to a cutting corner to increase a clearance of the cutting tool during a machining operation, thereby reducing wear on the cutting tool.
