Abstract
A drill rod can include a body having an outer surface, an inner surface, a longitudinal axis aligned with a drilling axis, and at least one longitudinally extending groove extending radially outwardly from the longitudinal axis relative to the inner surface. The inner surface and the at least one longitudinally extending groove can cooperate to define an interior space through which an inner assembly can be received as the inner assembly is advanced and retracted relative to the drilling axis. The at least one longitudinally extending groove of the body of the drill rod can be configured to permit axial flow of fluid through the drill rod as portions of the inner assembly engage the inner surface of the body of the drill rod.
