Double tube core barrels T2
The T2 core barrel is a double tube core barrel with the inner tube mounted on bearings. The preservation of the core is its’ main advantage. Available in the outer diameters ranging from 46 to 101mm, its’ thin kerf design allows a high penetration rate, a lower diamond cost and a larger core than the series T6.
Double tube core barrel of T6 type

The diameters range from 76 to 146mm.The core barrels in the diameters ranging from 101 to 146 can be converted to Triplex core barrels by adding another type core lifter and core lifter case, an adequate drill bit and a transparent Plastic liner within the inner tube.
