Abstract
An oven for the partial heat treatment of tools, for example, twist drills, omprises a first section, which contains the heating chamber that is constantly at the desired operating temperature. A second section for the loading and unloading and the quenching is provided. Between the two sections there is arranged a transport device for the charges of tools. The oven may be in the form of a one-chamber or three-chamber vacuum oven. The oven provides a high heat transfer rate, because the heating chamber is constantly at the desired operating temperature and the heat transfer by heat radiation under vacuum is started immediately when the charge is at its final position inside the heating chamber.
