The invention relates to a method for producing a commutator ring (10) for a commutator of an electrical machine, in which the laminas (12) of the commutator ring and fastening means (18) are formed out of a band material (27), and a selectable number of laminas (12) are then closed to form the commutator ring. The fastening means are produced with a special tool (35) in the form of dovetail grooves (22) by means of a so-called furrowing operation, which is done simultaneously from both face ends of the laminas (12).
