PQ Natural Diamond Reaming Shells for Wireline Coring Drilling

PQ Natural Diamond Reaming Shells for Wireline Coring Drilling​




PQ Reaming shell products is a combination of synthetic diamond grit, thermally stable polycrystalline (TSP) synthetic diamond elements and tungsten-carbide wear pads. These materials are cast into a tough, abrasion resistant matrix body. Unlike some reaming shell designs that employ natural industrial diamond particles, PQreaming shells are set entirely with synthetic diamond materials that have known engineering properties. This feature makes the our PQ reaming shell well suited for use on drilling projects in which the potential for contamination by natural diamond crystals is considered objectionable.
