A rotor end piece ( 1 ) for rotors ( 2 ) of thermal turbormachines is provided with circumferential slot ( 3 ), including two end piece halves ( 4, 4 ') having side faces ( 5, 5 ') opposite one another in the installed state and top surfaces ( 6, 6 ') adjoining one another. The rotor end piece ( 1 ) side faces ( 5, 5 ') of the end piece halves ( 4,4 ') are connected to one another in a form-fitting manner. To this end, the side faces ( 5, 5 ') are designed in such a way that a dovetail interlocking connection of the two end piece halves ( 4, 4 ') is preferably realized. The interlocked end piece halves are then secured with a weld ( 8 ). The firm anchoring of the rotor end piece ( 1 ) achieved in this way prevents detachment during operation and damage to the turbomachine caused as a result.
