Key Features
Efficient, reliable, and low-effort core drilling with Wire-line systems – performance improves with depth
Wire-line core drilling tools can lift core from drill rods without picking up coring system. A complete set of wire-line drill tools include: Core barrel assembly, overshot assembly, drill rods, holding dog, hoisting plug, circle wrench etc. It has some advantages such as high penetration rate, high penetration rate, high core recovery ratio, long bit life and lower labor intensity. The advantages can get more clear with the increasing of drill hole depth.

Application
Stop ring
This ring ensures that the core lifter stays in the core lifter case. It is easily inserted into the grooved space provided in the core lifter case.
Core lifter case
The core lifter case is essential when it is time to break the core sample. Its tapered interior prevents the core lifter from moving and allows it to keep its grip on the core sample.
Slotted core lifter
The inside of the core lifter is available in a slotted style, which is ideal for competent soil.
slotted and fluted (also known as broached), to ensure a good grip regardless of the ground conditions. A core lifter that is slotted is good for competent soil whereas a fluted core lifter provides better recovery in fractured ground.
Fluted core lifter
The core lifter can be purchased in a broached style (also known as fluted), which provides better recovery in fractured ground.
Locking Couplings
The locking coupling adapts the core barrel outer tube to the drill rods and locks the head assembly to the outer tube so that the head assembly turns with the outer tube when drilling. It also stabilizes the upper section of the core barrel, minimizing hole deviation and some types can protect the hole diameter if the reaming shell loses its gauge.
Rod Recovery Tap , Male Tap
The Rod Recovery Tap is an emergency tool for retrieving stuck rods from the borehole, allowing drilling to resume quickly.
Hosting Plug
Designed for lifting operations, the hoist plug accurately positions drill rods in the borehole and enables safe retrieval of rods or casing.
Subs Adapter
Subs Adapters seamlessly connect drill rods, core barrels, casing, bits, water swivels, hoist plugs, and rod recovery tools into one integrated system.
Inner Tube Stabilizer
Inner tube stabilizer mounts in the reaming shell, centering the inner tube above the bit for seamless core entry. Bearing isolates stationary inner tube from rotating outer tube.
Diamond Locking Couplings, Backend Reamer
Engineered with diamond-reinforced wear protection and a precision lock, this coupling resists loosening, cuts friction, and delivers reliable deep-hole connections. Perfect for hard, abrasive rock.
Adaptor Couplings
A durable alloy steel adapter coupling that links the locking coupling with the outer tube and features latch recesses for head assembly engagement.
Outer Tube Wrench, Rod Wrench
Tighten or loosen joints fast with these long-lasting tube wrenches. Gripper pads or particle reinforcement ensure a secure grip on both inner and outer tubes.
Diamond Inner Tube Wrench
Tighten or loosen joints fast with these long-lasting tube wrenches. Gripper pads or particle reinforcement ensure a secure grip on inner and outer tubes.
18‘‘ , 24’’ , 36‘’ , 48‘’ Tube Wrench
Slip-free operation for inner/outer tubes. Reinforced with gripper pads or particle coating. Available in 18″, 24″, 36″, 48″. Designed for durable wireline coring use.
One primary application occasion for the wireline core barrel is in geological exploration projects. Whether you are conducting mineral exploration, geological surveys, or environmental research, this core barrel assembly is designed to deliver accurate and high-quality core samples. The barrel’s screw/unloading rod/casing function ensures smooth and efficient drilling operations, making it an indispensable tool for geologists and exploration teams.
Another common scenario where the wireline core barrel excels is in the construction industry. With a core length of 1.5m or 3m, this tool is ideal for obtaining core samples from different depths during construction projects. The adapter subs compatibility with BQ, NQ, HQ, and PQ sizes allows for seamless integration with existing drilling equipment, making the core barrel assembly a convenient choice for construction sites.
