ABSTRACT:
A nozzle retention system for a drill bit which includes a nozzle member which is retained by means of a keyway in the bit body. The bit body can include a partially cylindrical bore, truncated by opposing walls to form a lower contact surface within the bit body. The nozzle will be conformed to pass through the bore in a first orientation, and to be retained in the bore and against such contact surface when the nozzle is rotated to the second orientation.
