Claim Text:
1. A metal-cutting tool having a center axis, comprising: a cutting part having at least one peripherally arranged cutter which, upon an imaginary rotation about the center axis, defines a cutting circle of nominal diameter; and at least one peripherally arranged guide element which viewed in a cross section lies on a guide circle, the center of which is either arranged eccentrically to the center axis by an eccentricity or which has a larger diameter than the cutting circle, wherein the at least one peripherally arranged guide element includes two guide elements that are arranged, with which the metal-cutting tool in the metal-cutting operation is supported against a workpiece, and which are spaced apart at an angular distance (δ), the amount of eccentricity (E) being determined according to the formula: E=0.5*(D1−D2)*cos(0.5*δ), wherein E is the eccentricity, D1 the diameter of the cutting circle, D2 the diameter of the guide circle and δ the angle between the guide elements.
