ABSTRACT:
A nozzle assembly for use in a drill bit includes a nozzle body having a nozzle oriented at an angle to the longitudinal axis of the nozzle body and a positioning ring that is rotationally and axially locked to the nozzle body. The nozzle body includes a plurality of facets extending between a pair of retention surfaces. The positioning ring has a plurality of teeth and is operatively disposed between the retention surfaces to axially retain the ring on the nozzle body. When positioned between the retention surfaces, the teeth engage the facets to rotationally lock the ring to the nozzle body. The positioning ring may have a longitudinal split, to allow the ring to ratchet relative to the nozzle body, and a pair of spanner-receiving apertures. In operation, the ring is coupled to the nozzle body and the resultant assembly is coupled to the drill bit. Any misalignment is noted and the assembly is removed from the drill bit. A spanner wrench may be used to rotate the ring relative to the nozzle body to compensate for the misalignment. The assembly is then recoupled to the drill bit with the nozzle in the preferred orientation.
