Product Description

The 73mm DZ240 Core Barrel is a specialized drilling component designed for core drilling operations. This core tube attaches to the top of the drill bit to securely hold and protect the core sample while serving as a guide tool during drilling operations.

A standard core tube consists of a seamless steel tube with wire connections at both ends, featuring a diameter slightly smaller (2-4mm) than the drill bit. Single core pipes typically measure 3-45 meters in length. For enhanced stability and to prevent drilling hole bending, multiple core pipes can be connected to form longer, thicker diameter drilling tools.
