Abstract: A tool post of a machine tool, in which the tool post is capable of receiving a cutting insert for machining a component, is provided. The tool post includes at least one sensor capable of determining a parameter representative of a cutting action between a component to be machined and a cutting insert; and a support housing which is electrically connected to the sensor and includes a battery and a printed circuit board supplied with current by the battery. The printed circuit board supports, at least partially, a radio transmission unit. The housing includes a base and a cover which can be detached from one another. The battery is supported by the cover and the printed circuit board by the base or vice versa.
