The invention relates to a whirling tool (10) for the metal-cutting machining of a workpiece, comprising three, or a plurality of three cutting plates (14a, 14b), wherein each of the cutting plates (14a, 14b) has at least one cutting edge (42a, 42b); a cutting plate carrier (12) having a plurality of cutting-plate receptacles (26) for respectively receiving one of the cutting plates (14a, 14b), wherein the cutting-plate receptacles (26) are arranged distributed over the cutting plate carrier (12) in the circumferential direction (20); and a plurality of fastening elements (16) for detachably fastening the cutting plates (14a, 14b) in the cutting-plate receptacles (26) of the cutting-plate carrier (12). The cutting plates (14a, 14b) comprise at least two different kinds of cutting plates (14a, 14b), wherein at least one cutting plate (14a) of a first kind and one cutting plate (14b) of a second kind, each a group of three adjacently arranged cutting plates (14a, 14b) are provided on the cutting-plate carrier (12). The cutting plate (14a) of the first kind differs from the cutting plate (14b) of the second kind by the overall geometry of the cutting plate (14a) of the first kind, by a dimension of the at least one cutting edge (42a, 42b), and/or by a shape of the at least one cutting edge (42a, 42b).
