Diamond Reaming Shell Diamond Reaming Shell is a very important reamer tool to be used together with core bits in core drilling.It's set with natural or synthetic diamonds.The new design includes T.C. type, PCD type and Electroplated diamond type.its main application 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 , improving drill rods stability and protecting lower part of drill rod from excessive wear. 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.
