Reaming Shell:

Reaming shell is set with natural or synthetic diamond, and the new type also have T.C. type, PCD type and Electroplated diamond type for choose. It is used to couple the drill rods with the core barrel. Its main function is to ream the hole to the correct constant specific diameter which ensures adequate clearance for the core barrel and sufficient clearance for the new bit which replaces an old one. It also acts as a stabilizer for drill bits and drill rods.

Reaming shells (with double tube core barrel or triple tube core barrel) are suitable to use in all formation conditions ranging from broken and abrasive to consolidated and non abrasive.

Combined high quality and design make our reaming shells the best in the industry. With several different types, we've got you covered no matter what your requirements are.
