Home >> Core barrels >> WF Series Double Tube Core Barrels

Double tube core barrels: WF Series Double Tube Core Barrels are geotechnical core barrels primarily designed for coring in relatively soft formations by using face-discharge bits. With simple construction they’re more resilient to damage than thin-wall barrels, but with slower penetration rate.
