WM Series Double Tube Core Barrels

WM series double tube core barrel was developed as a solution to the ever present problem of recovering a high percentage of core when drilling badly fractured or broken strata or soft and friable material that is easily eroded by the circulating fluid. Mud or water can be used with this core barrel while drilling. It has more sturdy design compared to the metric series core barrels.
