Diamond core drill bits and reaming shell/ reamer with IMP & Surface set
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.
Our reaming shells experience longer life in the field due to the greater number of diamonds and high-grade carbide reinforcements.Our diamond impregnated reamers feature large synthetic stones concentrated on the surface of the reamer pad.
Size: Tangshan Jinshi reaming shells are available in all standard drilling sizes(BQ,NQ,PQ,HQ) as well as a number of region-specific sizes.
Compatibility
Our diamond bits and reaming shells are designed to be compatible with all standard core barrels from other suppliers.
