Methods and device for producing a thread, comprising a gear unit

A tool holder has a first holder part for inserting into a receptacle in the machine tool and a second holder part for holding a tool. The tool holder has a conduit for directing a coolant and/or lubricant to the tool from a coolant and/or lubricant source. The tool has a conduit section for the coolant and/or lubricant for directing the latter to a machining point, and wherein, in the fitted state of the tool in the tool holder, the conduit is in contact with the conduit section at a coupling point. Provision is made for there to be an air feed line which directs compressed air from a compressed-air source into the region of the coupling point in such a way that the compressed air acts on the outer circumferential surface of the conduit and of the conduit section. Furthermore, methods for operating such a tool holder are described.
