T2 76, 86, 101 Double Tube core barrels for hard rock formation drilling
T2 Series core barrels
Double tube
T2 double tube core barrels are widely used and suitable for coring in all hard and soft formations, with water flushing and/or polymer fluid. The thin walls provide fast penetration, lower bit cost and larger core sample.
They are in accordance with the metric standards ISO 3552-1.1992.
All spare parts and accessories for T2 core barrels are manufactured from the best quality raw materials.
The inner and outer tubes are manufactured from cold drawn seamless steel tubes with very high tensile strength and straightness providing the same properties as our drill rods and casing tubes.
Core lifters (springs) are available in standard and in basket type. Basket type is suitable for very soft and fine grained formations.
Core lifter cases can be case hardened to increase their wear resistance, upon special request.
Available in sizes 101, 86, 76, 66, 56, 46 & 36mm.
