Mining Diamond Drilling Tool, Bq Nq Hq Pq Wireline Core Barrel/Overshots

Basic Info

Product Description

Core Barrels include single tube type, double tube type and triple tube type.

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.

Overshots:

Overshot is a necessary device in wireline drilling. It is dropped on a cable and directly couples onto and lifts up the inner tube assembly, eliminating the need to couple and uncouple the rod string each time the core is retrieved.
