There is a difference between a pure waterjet nozzle and an abrasivejet nozzle. Waterjets also commonly cut stone and glass, because the waterjet can get intricate shapes not possible using traditional machining methods. There are no noxious fumes, such as vaporized metal, and no risk of fires. The distance between the end of the waterjet nozzle and the material is typically very small, although caution is needed when the waterjet nozzle is raised.
