MACHINED HIGH ANGLE NOZZLE SOCKETS FOR STEEL BODY BITS

摘要

An apparatus that includes one or more machined high-angle sockets and method for fabricating such sockets. The apparatus includes a body, one or more blades extending outwardly from the body, and one or more high-angle nozzles machined into a portion of the blade. The body includes a bit face at one end and a plenum formed therein communicably coupled to an opening formed at an opposing end. Each blade includes a leading section, a trailing section, a face section extending from one end of the leading section to an end of the trailing section, and an inner section extending from an opposing end of the leading section to an opposing end of the trailing section. Each nozzle includes a nozzle socket cavity and a second hole intersecting with the nozzle socket cavity and extending to the plenum, which collectively form a passage extending from the plenum to the bit face.
