Diamond core drilling triple core barrel

T2 Series Core Barrel T2 series double tube core barrels are suitable for coring in all formation types. The core barrel is designed for use with core bits with a thin cutting face in order to maximize the rate of penetration. Suitable for use with water or mud as the flushing medium.

The T2 series corebarrels are available in metric sizes 56 - 101 mm, and DCDMA hole sizes B and N. The latter are denoted TBW and TNW, respectively.

The Lifter Case is a push fit directly onto the Extension Tube. When the core is broken from the rock strata, the Lifter Case slides down to rest on the Core Bit. Thus the entire load of the core is transferred to the Outer Tube. This design is especially advantageous when working with heavy cores as it prevents overloading the bearings and thus prolongs the life of the core barrel.

The Inner Tube and Outer Tube are manufactured from cold drawn steel tube with a very high tensile strength and straightness. The Head Assembly is manufactured from heat-treated alloy steel to ensure long life.

As an option T2 series core barrels can be used with clear plastic Coreliner tubes to form an inner, triple tube.This greatly facilitates core handling and improves presentation. When Coreliner tubes are used an undersized bit and corelifter are required.
