Diamond Reaming shells NQ HQ PQ
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.
Diamond Reaming Shells are very important reamer tools to be used together with bits in core drilling. Its main functions are maintaining the borehole gage, improving drill rods stability and protecting lower part of drill rod from excessive wear.
Helical type reaming shells provides good passages for water flowing, the matrix is wear proof and its service life is long.
