ABSTRACT:
A nozzle for a drill bit comprises a nozzle body and a ring for securing the nozzle body in a threaded cavity of the drill bit. The nozzle body includes a fluid passage of the orientable type. The ring comprises an externally threaded sleeve and a cap bonded to a front end thereof. The cap and nozzle body are formed of harder materials than the threaded sleeve. The cap contains dove-tail shaped slots for receiving complementarily shaped projections on a tool to enable the ring to be rotated relative to the nozzle body. By threading the ring into the cavity, the nozzle body can be secured in the cavity with its fluid passage oriented in the desired final orientation.
