ABSTRACT:
A non-plugging nozzle and self-cleaning drilling tool incorporating the nozzle is provided. The nozzle has a body that defines a central passageway extending axially from the top to the bottom of the body. The central passageway defines an inlet orifice at the top and an exit orifice at the bottom. A side passageway extends through the side wall of the nozzle and communicates with a cylindrical portion of the central passageway, the intersection of which defines a side inlet orifice that is substantially square. Because the intersection is substantially square, particles may not become trapped within the nozzle and plug the side passageway. When incorporated into a drilling tool, particularly a polycrystalline diamond compact (PDC) bit, the drilling tool becomes self cleaning. The side passageway of the nozzle is directed at the voids formed in the cutting face of the drilling tool creating a cross flow through the voids and preventing accumulation and balling therein.
