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 labour intensity. The advantages can get more clear with the increasing of drill hole depth.

We can supply BQ, NQ(3), HQ(3), PQ(3), NQ2, NQ2U, BQU, NQU, HQU, T2-76, T2-86, T2-101, LTK48, LTK60 corebarrel.

Brief Introductions of Core Barrels
Our core barrels include wireline (Q series), T2-76, T2-86, T2-101, LTK48, LTK60 core barrels. We also provide core barrel parts such as core lifters, core lifter cases and locking couplings. This kind of core drill strictly complies with the international standards. Core drilling tools can lift core from drill rods. During this process, picking up coring system is not necessary. Core barrel assembly, overshot assembly, drill rods, holding dog, hoisting plug, circle wrench are all belong to drill tools.

Features of Core Barrels
1) High penetration rate and high drilling efficiency.
2) High core recovery rate.
3) Long bit life and lower labor intensity.
4) Adopt abrasion resistant material.
