Abstract: A down hole forward and back scuttling tool capable of being removably connected to a power driven drill string and to an expandable reamer to transmit torque from the drill string to the reamer as the latter is transversely expanded and rotated to form an elongate cavity in the lower portion of the bore hole. The reamer is of a conventional type that permits fluid under pressure to discharge therefrom. The tool during the reaming operation permits fluid under pressure to flow downwardly in a first path through the drill string, tool and reamer to exit from the latter into the cavity and then upwardly through an annulus shaped space defined between the side wall of the bore hole and drill string to the ground surface. Cuttings from the reaming operation drop downwardly due to gravity to the bottom of the cavity. It is desirable that such cuttings be removed from the cavity prior to the latter being packed with gravel. The tool permits these cuttings to be retrieved.
