To provide a nozzle for supplying processing mist of a processing device, which sufficiently supplies the processing mist to a blade part of a tool for processing the inner surface of a hole of a workpiece.
In the nozzle 20 for supplying processing mist of the processing device, the mist for processing is supplied to the tool 12 when the inner surface of the hole 32 of the workpiece 30 is machined with the tool 12 while moving the tool 12 in the longitudinal direction in such a state that the tool 12 such as a broach or the like of the processing device 10 is inserted in the hole 32 of the workpiece 30. An exhaust nozzle 23 for mist for processing of the nozzle 20 is formed to be annular for surrounding the central shaft 19 in the longitudinal direction of the tool 12, and the processing mist is jetted from a processing mist jetting port 23 toward the tool 12.
