Abstract

A continuous coring drill bit having a body forming external lands for support of cutting elements such as industrial diamonds and grooves for conducting drilling fluid during drilling. The body further forms an internal cavity receiving a tubular core breaker in freely rotatable relation therein and also forms a central throat receiving a core as the drilling operation continues. The core breaker is provided with an internal buttress and is eccentrically mounted within the body such that rotation of the body induces lateral oscillation of the buttress causing it to fracture the core into small sections. By reverse circulation the core sections are transported upwardly through the drill string to the surface for separation from the drilling fluid and analysis by geologists.
