AQ,BQ,NQ,HQ diamond reaming shell/economical reaming shell
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.
