Patent ID: 7114583

Claim:
An apparatus for drilling, reaming, or cutting, comprising: a) an orbital housing including a central passageway, said central passageway adapted to receive a multitude of pressurized drilling mixtures of fluid, gas, and solids, at a multitude of pressures and temperatures, from an external supply, said orbital housing central passageway to convey said multitude of pressurized drilling mixtures of fluid, gas, and solids, at said multitude of temperatures, to a generally vertical passageway and to a generally horizontal passageway; b) a substantially circular orbital member freestanding within said orbital housing, said orbital member including a main bore to receive said multitude of pressurized drilling mixtures of fluid, gas, and solids, at said multitude of pressures and temperatures, from said vertical passageway and convey same out the distal end of said orbital housing, said multitude of pressurized drilling mixtures of fluid, gas, and solids, at said multitude of pressures and temperatures, from said horizontal passageway urging said orbital member to orbit and gyrate, with slight counter-rotation of the substantially circular orbital member in the opposite direction of said orbital member rolling within the substantially circular interior of said orbital housing, thereby minimizing relative movement, friction and wear between the orbital member and orbital housing, said multitude of pressurized drilling mixtures of fluid, gas, and solids, at said multitude of temperatures, from said horizontal passageway urging said orbital housing to orbit and gyrate, whereby drilling, reaming and cutting of target materials, cuttings removal, bore wall reinforcement, and smoother straighter bore holes are achieved.
