Reaming Shells
Reaming shell is set with natural or synthetic diamond,and it is used to couple the drill bit 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 bit.
We can produce reaming shells with 6", 10" and 18" length.
Reaming shells (with double pads or three pads) are suitable to use in all formation conditions ranging from broken and abrasive to consolidated and non-abrasive. As this kind of reaming shell is physically longer than the standard type, it is necessary to use an appropriate inner tube extension in order to compensate for the difference in overall reaming shell length.
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.JESSIN can make four type of reaming shells,it include:
1.Surface Set Diamond Type
2.Electroplated Diamond Type
3.Tungsten Carbide Type
4.PDC Type
