Abstract
A nozzle for a drill bit such as may be used to drill for oil or natural gas. The nozzle includes a generally-cylindrical body having a longitudinal axis, a proximal end for insertion into a drill bit body, and a distal end opposite the proximal end. The nozzle body defines a longitudinal bore through the nozzle along the longitudinal axis. The nozzle further includes one or more lobes extending radially from the nozzle body near the distal end. Each of the lobes is displaced axially from the distal end such that a cylindrical portion of the nozzle body is disposed between the distal end and the lobe. The nozzle further includes a fitting in the distal end configured to engage a tool for imparting rotational torque to the nozzle about the longitudinal axis. Such a nozzle is preferably insertable into a drill bit body from outside the body.
