High pressure fluid jet drill system

A high pressure fluid jet drill head comprising:

• a body having a first circular end and a second circular end, wherein the second circular end has a lesser diameter than the first circular end;
• a conical surface extending from the first circular end and the second circular end;
• a central fluid inlet disposed within the body proximate the first circular end and extending along a central axis toward the second circular end;
• at least one nozzle in fluid communication with the central fluid inlet, the at least one nozzle disposed on the conical surface.

A high pressure fluid drill head for cutting debris to form a bore hole comprising:

• a body having an upper end and a lower end, an interior surface, and an exterior surface;
• and
• a nozzle disposed on the exterior surface of the body;
• wherein the body defines a plurality of flow paths, the plurality of flow paths comprising a first flow path, one or more second flow paths, and a third flow path, wherein:
• the first flow path is configured to return debris through the body;
• the one or more second flow paths in fluid communication with the nozzle, the one or more second flow paths configured to deliver pressurized fluid to the nozzle to perform the cutting operation;
• the third flow path in fluid communication with the one or more second flow paths and the first flow path, the third flow path configured to divert a portion of the pressurized fluid from the one or more second flow paths into the first flow path;
• wherein the portion of pressurized fluid diverted through the third flow path into the first flow path generates a pumping action within the first flow path to draw debris into and upward through the body.
