Product Description:
Using quality natural diamonds set in a very resistant matrix, the natural diamonds sections are acturally cast into the matrix and become an integral part of the shell. It ensures maximum performance as the shell will maintain a full gauge hole in all types of grounds.
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.
