BTW THIN WALL WIRELINE DOUBLE TUBE CORE BARREL
A drilling core barrel is a cylindrical tool used in drilling operations to extract cylindrical samples of rock or soil from the earth's surface. The tool consists of a hollow barrel with a cutting bit at the bottom and a core lifter at the top. The cutting bit cuts through the rock or soil, and the core lifter holds the cylindrical sample in place as it is extracted from the ground.
