Product Description

1. TT Series Core Barrel                                                                                                                       Ultra-thin walled double tube core barrels, available diameters 46 and 56 mm. Very thin cutting face allows very rapid rate of penetration through hard formations.They are suitable forunderground  mining applications.

2. T2 Series Double Tube Core Barrels
  The T2 Series are thin wall double tube core barrel, used for surface exploration, especially mining applications. Due to their thin kerf, these core barrels provide rapid penetration. Available in diameters  46, 56, 66, 76, 86, 101mm.

3. LTK 48 & LTK 60 Double Tube Core Barrels
  The LTK series core barrels system is a thinner wall core barrel than T2 series. They offer a cost effective, high production, which is designed for optimum production and core recovery in medium to extra hard  rock formations. Available sizes 48 and 60mm.

4. WF Series Double Tube Core Barrels
  They are geotechnical core barrels primarily designed for coring relatively soft formations in using face-discharge bits. Simple construction and more resilient to damage than thin-wall barrels,but with slower  enetration rate.

5. WG Series Double Tube Core Barrels
  There are Double tube core barrels for WG series. Available in DCDMA sizes E, A, B, N,  and H.

6. TBW and TNW Core Barrels
  These are thin-walled double tube core barrels, as T2 series but with DCDMA hole sizes B and N. Used for surface exploration,  specially mining applications. The thin kerf area allows rapid penetration.

7. Wireline Double Tube Core Barrels
   Wireline double core barrels are primarily used in deep coring. With an overshot device, they eliminatethe need to couple and uncouple the rod string each time the core is retrieved. Available in DCDMA sizes A, B, N, H ,and P.
