- Impregnated Synthetic Diamond Core BitsImpregnated diamond core bit has become the most commonly used core bit in mineral exploration industry. CDG’s diamond drill bit performance is the product of many years of research. It coordinates diamond grading and selecting technology, bit design, matrix composition and manufacturing process with...
- Surface-Set Diamond BitsSurface set diamond bit is mainly used for drilling formations of medium hardness and high hardness. Its main components are large diamond particles, steel body and carbide powder. Diamonds are quite suitable for making drill bits with complex shapes. The diamonds are mounted in a bit crown powdered...
- PDC Core BitsPDC drill bit (polycrystalline diamond compact drill bit) is mainly composed of steel body and polycrystalline diamond composite sheet. Polycrystalline diamond bit consists of a designed cast matrix head to which PDC inserts have been fixed. The surface of this disc-shaped cutting element consists of very...
- Rod Shoes and Casing ShoesCDG casing shoe is manufactured in impregnated diamond, surface set, TSP cube set, and tungsten carbide types. It is employed to seat the casing tubes in bedrock or to ream the casing tubes downward in a drilled hole. It assists in seating the drill casing into bedrock, and providing a tight seal for the...
- Reaming ShellsReaming shell is mainly made up of steel body, polycrystalline diamond and carbide powder. It is manufactured with high-quality synthetic and natural diamonds which are embedded in a highly resistant matrix. 6" (one pad), 10"(two pads) and 18" (three pads or four pads) and oversize CDG reaming shells in industry...
- Drill RodsOur wireline drill rods are manufactured from highest quality cold drawn alloy seamless steel pipes. Harding the thread and special heat process on pin thread and tube surface. Drill rods are available in standard length of 3mtrs, 1.5mtrs, 5ft and 10ft. Shorter lengths (like 1mtrs, 0.75mtrs, 0.5mtrs...
- Core BarrelsCDG manufactures double tube and triple tube core barrels in length of 6mtrs, 3mtrs and 1.5mtrs. Water in double tube core barrel is injected between outer tube and inner tube. Perforation at the lower end of inner tube permits flow of water. From this point to diamond core bit is the only place which...
- Double Tube Core BarrelDouble tube core barrels are swivel head. The inner tube is attached with the core barrel head through bearings which makes the rotation of inner tube independent of core barrel. It serves to improve the rate of collection. Core barrels are designed for coring from soft to hard homogenous and slightly...
- Triple Tube Core BarrelTriple tube core barrel consists of outer tube and inner tube assembly. It is made up by adding a third tube to the standard wireline core barrel. This third tube is made of stainless steel, which is split lengthwise and nested inside the inner tube.Triple tube wireline core barrel...
- BZU NZU Core BarrelZU core barrel is suitable for drilling in tunnels. It is a superior tool for site investigation in soft to hard formations.1. It can drill holes upward or horizontally.
2. It has fast penetration speed compared with thicker wall core barrels.
3. ZU core barrel is suitable for various rock formations...
- OvershotsOvershot is one of the necessary equipment for wireline drilling which could be put into the hole. This fishing tool is used to connect with the inner tube assembly and lift it up. Overshot is attached to drill rod and lowered over the pipe or stuck in the borehole. Hardened and self-cutting threads...
- Water SwivelsWater swivel have passed destructive testing and ISO9001 standards. Security and reliability are guaranteed. It is made up of pressure-sealed ball bearings, precision machined alloy-steel spindles,with harder coating. It is designed to facilitate the introduction of coolant (normally water) to the...
- Hoisting PlugsHoist plugs have passed destructive testing and ISO9001 standards. Security and reliability are guaranteed.They are designed for use with drills equipped with main hoist. They are used for raising and lowering drill strings. The hoisting plug is a frequently-used wireline core drilling equipment...
- Casing Cutter AssemblyThe casing cutter assembly is for cutting steel pipe underground. Our unique downhole hydraulic pipe cutter applies smooth constant pressure onto three knives via a piston assembly, thereby assuring clean and rapid cutting. Once the device is lowered to the desired depth where water pressure can be...
- Adapter SubsAdapter subs are important wireline core drilling parts in drilling operation. They are used as connectors or couplings to connect drill rods, core barrels, casing, rock bits, water swivel, hoisting plug, fishing tools, etc. TallKee Geological Equipment (CDG) produces a wide range of sub...
- WrenchesA wide range of full grip wrenches are available in CDG. They are designed for use with inner and outer tubes. There are diamonds or tungsten carbides on the grip wrench surface which are used to protect the tubes surface from being damaged...
- Recovery ToolsRecovery tools are mainly used for salvaging drill rods and casing tubes. The recovery taps are designed to be inserted in broken rods and barrel parts. We have BO/NO/HO/HWT rod taps fro your selection...
- Foot ClampsThe foot clamp, also called drill rod holder or drill rod clamp, is able to clamp every position of drill rod. This device is suitable for core drill rigs and drill rods used in geological exploration of soft soil engineering...
