The fluid perforating /cutting nozzle is configured to provide long life to the nozzle. The nozzle is composed of a cylindrical shaft defining a bore for the passage of cutting fluid and having inlet and outlet ends, a shank portion and a relatively large diameter shroud disposed on the outlet end. The shroud protects both the nozzle and the tool from the high pressure cutting fluid reflecting off the surface of a workpiece.
