RDS Engineering manufactures diamond Reaming shells for NMLC triple tube for Diamond Core Drilling, Tunnel Drilling, Geotechnical Investigation, Soil Testing, Drainage, and Grouting of Holes, among other uses. The reaming shell, which is immediately above the diamond core bit, keeps the drill hole's outer diameter constant. The diamond core bit is joined to the core barrel by the diamond reaming shell. The reaming shell effectively reams the hole because its outer diameter is only a little bit larger than the core bits. The reaming shell serves as a link between the core bit and the outer barrel and is a crucial component of a diamond drilling system. In addition to stabilizing the drill string's bottom, it reams the hole to the right size. The drilling crew should regularly inspect the reaming shell's outer diameter since a worn-out or smaller reaming shell will cause the drill bit and drill string to become stuck. RDS manufactures great-quality synthetic and natural diamonds that are placed in a matrix with great resistance and is used to create reaming shells. On the leading edges of the ring, friction-resistant tungsten carbide inlays offer extra security and a longer lifespan. Diamond reaming shell for NMLC triple size core diameter of 48 mm and a Drilling hole diameter of 76 mm.

Use: For approximately 100% core recovery, the Triple Tube Core Barrel is utilized for mineral research, geotechnical study, diamond core drilling, soil analysis, testing of high-rise construction foundations, and exploration of dams and bridges. Method: The reaming shell, diamond core bit, and core lifter casing are taken out once the triple tube barrel has been taken out of the drill hole. The third, or split tube, is forced out using a piston mechanism after air or water is poured into the head. The top half of the split tube is then raised, showing the core in its original state. RDS Engineering manufactures the following Triple Tube Core barrels: • BMLC Triple Tube Core Barrel • NMLC Triple Tube Core Barrel • HMLC Triple Tube Core Barrel Specification and standard size: NMLC Triple Tube Core Barrel core diameter of 48 mm and a Drilling hole diameter of 76 mm.

Nx diamond casing shoe bit The diameter of these bits is smaller than that of casing shoes, preventing the core barrels from passing through. Nx Diamond casing shoe bits are made to open the hole, drill it down normally, and place standard casing tubes of various diameters in specific drill holes. While diamond rod shoe bits and casing shoe bits are extremely similar, the thread connections on the former are different, and the latter is mostly used for wireline drilling rods. Diamond-coated casing shoe bits: The inner sides of the casing shoe bits are flush with the casing's inner diameter and are NOT set with diamonds. Corresponding-sized core bits and core barrels can readily pass through the casing shoe bits' inner diameter. The diamond grits are used to create a diamond casing, as well as casing shoe pieces. The bit's core and matrix both include these diamond grits, which are attached by a powdered metal bond. For opening holes, surface-set diamond casing and casing shoe bits are manufactured. Natural diamonds are put on the bit crown to create a surface set diamond casing and casing shoe bits.
