摘要：
Subterranean drill bits and particularly to nozzle features to be incorporated in subterranean bits. In one embodiment, the nozzle assembly of the invention defines a wear resistant structure which extends upstream from the terminus of the transition area. In another embodiment, nozzle assemblies are arranged about the transition area at low angles so as to minimize flow turbulence.
