Exploration Geological Coring Single Link Natural Diamond Tanged Locking Couplings BQ NQ HQ PQ

Diamond Locking coupling is the part of the core barrel that is found on the upper part of the outer tube. 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.

The primary function of the locking coupling is to lock the inner tube into position for core retrieval, it also acts as a backup for stabilization. The supporting pads provide maximum stability to the core barrel while the waterway design optimizes flushing to the bit.

Wireline core barrels eliminate the major time consuming operation of using standard double tube core barrels – pulling, stacking and lowering drill rods each time the core barrel is full.

Using a wireline system, core is recovered quickly by retrieving the core-laden inner tube directly through the drill string. The rods remain in the hole until the bit needs to be replaced. This has major cost advantages when drilling deep holes for mineral exploration.

These core barrels are available in industry standard hole sizes A, B, N, H and P. All parts are fully interchangeable with most other manufacturers’ wireline core barrels. Special requirements can also be met on request.
