Abstract (en)
A gouging cutter (18) includes a cutting element (18B) having a cutting end (118) and a mounting feature displaced from the cutting end (118) and a cutter body affixable to a drill bit body (11). The cutter body has a corresponding mounting feature arranged to cooperate with the mounting feature on the cutting element (118) to retain the cutting element (118) to the cutter body so as to enable rotation of the cutting element (118) therein. A drill bit may include a bit body (11) having features to enable connection to a drill string and at least one of the foregoing gouging cutters (18) mounted to the bit body (11).
