Professional Wireline Drilling Core Barrel Stainless Steel For Mineral Exploration

Drilling Core Barrel Wireline Drilling Tools Deep Holes Mineral Exploration

Wireline drill tools can lift drill core from drill rods without picking up drilling rods and bits.All the tools include principal parts of the drill tools,over shot assembly ,drill rods.holding dog,circle wrench and etc,their advantages are higher penetration,higher core recovery ratio.Longer bit life and lower labor intensity,and the advantages get more clear with the increasing of hole depth.

This has major cost advantages when drilling deep holes for mineral exploration.

The head assembly provides: latching and pivoting spear point mechanisms to allow insertion and retrieval of the inner tube assembly, a bearing assembly to allow the inner tube to remain stationary and avoid sample damage while drilling, fluid pressure operating indications and fluid control valves.

All head assemblies incorporate a shut off valve assembly which provides a fluid pressure signal to the drill operator when the valve members are compressed, indicating a full or blocked inner tube.
