摘要：
A machine tool having a motor-driven machine spindle which can be rotated about a spindle axis. The machine spindle has a tool holder arranged at the face. A tool is exchangeably arranged on the machine spindle. The tool has a coupling element which is compatible with the tool holder of the machine spindle. The coupling element has a rear surface pointing toward the machine spindle. The machine tool has at least one galvanic contact point for the electric current or data transmission, the point being arranged between the machine spindle and the tool and rotating together with the machine spindle. The galvanic contact point has a contact element which is arranged at the face of the tool holder on the spindle side, and a contact element which is arranged on the rear surface of the coupling element on the tool side.
