ABSTRACT:
A hand held fluid jet drilling apparatus is described. The drill includes an elongated drill stem with a fluid jet nozzle on one end and a motor on the other end. High pressure fluid is supplied to the drill from an external power pack which also produces compressed air. The drill includes a high pressure swivel which allows the motor to rotate the nozzle while a continuous supply of fluid is present. The drill stem is spring mounted to provide protection to the operator. The swivel may also operate as an on-off valve which supplies flushing fluid while the drill is off. The drill is operable as a drill, reamer or slotting tool by suitable arrangement of controls. A second embodiment is illustrated which provides for continuous flushing with low pressure fluid during operation. The drill is also attachable to mechanical feed systems to extend face coverage.
