Zusammenfassung:	A nozzle for treating an interior of a workpiece by means of a highly pressurized fluid medium flowing out of at least one nozzle channel. The nozzle channel branches off from a supply borehole provided in the form of a blind hole. The nozzle is designed in such a manner that the nozzle channel, starting from the bottom end area of the supply borehole, extends at an angle less than or equal to 90° to the supply bore hole in the inflowing direction, the bottom of the supply borehole being provided with an elevation whereby narrowing the transition area to the nozzle channel.
