CASING ADVANCE SYSTEM
Roschen Casing Advance System features a simple, yet robust and proven design comprised of a Pilot Bit, a Casing Shoe and a Heavy-Duty Ring Bit. It's a concentric type overburden drilling system, which allows for the simultaneous advancement of casing as big as 24" in diameter, while drilling through fractured rock with a conventional down-the-hole air hammer. The pilot bit securely locks into the ring bit via special locking lugs to form the robust oversized-looking face of a conventional hammer bit – loaded with premium grade of carbide buttons. The unique locking mechanism also allows for direct transfer of energy from the hammer to the drilling surface of the ring bit and the pilot bit, which in turn ensures a superior penetration rate. The casing pipe is easily welded to the casing shoe, which threads into the ring bit to sit unrestricted on its shoulder, thus, preventing the casing pipe from rotating during the drilling operation and securing it at the same time. Depending on the drilling application, Drill King International customizes its casing advance system for either permanently left in the hole casing or retrieved (pulled-out) casing. Additional customization options are available based on the specifics of the drilling project, the actual casing and DTH hammer used, and the ground formation and conditions.
