T6 series core barrel comprises of a core barrel head, inner and outer tubes, extension tube, core lifter, reaming shell and core bit. Different types of lifters, reaming shells and core bits need to be selected according to the application and geology.

The T2 series is a range of components which produces 42, 52, 62, 72 and 84mm cores suitable for medium to hard geology. Water or polymer flush is required.

Designed for use in conjunction with metric casing the thin wall double tube core barrel is easily converted to a triplex system with the addition of a Coreliner for increased core recovery.

These core barrels have a relatively small cutting area and therefore permit rapid penetration, especially in harder rock formations. Also the thin wall barrels and core bits produce fewer cuttings which permits the use of lower flush velocities resulting in diminished sample disturbance.
