PEERCHEER offers BTW NTW HTW core lifter case for use with BTW NTW HTW core barrels. The BTW NTW HTW core lifter case mates to the inner-tube and houses the core lifter in a tapered socket which controls movement of the BTW NTW HTW core lifter. As the drill string is lifted during a core breaking operation, the core lifter case bottoms out on the inside of the drill bit transferring the pullback load from the drill string to the core lifter until the core sample breaks. TW series core lifter cases are available for application in standard DCDMA B N H size.
PEERCHEER’S core lifters are made of a high-quality alloy steel that is specially heat treated to increase strength,toughness, and wear life.
