Abstract
An apparatus and method for drilling an underground borehole where pressurized air may be used to discharge cuttings produced by a cutting assembly. The cutting assembly includes a shaft having a first and second ends and a bore extending between the ends. First and second cutting heads are provided on the shaft a distance apart. The second cutting head is rearward of the first cutting head and is of a greater diameter. Each cutting head defines an air passage therethrough that is in fluid communication with the shaft's bore. A housing extends rearwardly from the second cutting head and connects to a length of casing. An annular flange, concentric with the housing, seals the borehole as the cutting assembly rotates and moves forward through the ground. Cuttings generated by the assembly are moved therethrough and discharged from the casing by pressurized air provided to the assembly through the shaft's bore.
