Reaming Shell
We can not underestimate the importance of reaming shell in maintaining direction of gauge of the hole. It can extend the life of drill bit and has an influence on bit performance, so selecting the best available is an investment in productivity.
Our reaming shells are made by a team that understands the importance. Beset with natural or artificial diamond impregnated pads, they function as an important reaming tool used in core drilling system for to keep the borehole size up to standard, improve drill pipe stability and avoid excessive wear of lower part of drill pipe.
