Reaming shell, reamer shells
Reaming shell is set with natural or synthetic diamond, and it is used to couple the drill bit with the core barrel, main function of reaming shell is maintaining borehole gage, improving drill string stability and protecting lower drill string from excessive wear. Helical type reaming shell provides a good passage for drilling fluids, as the matrix is wearproof, its service life is long. We manufacture reaming shells, different patterns of PCD reamer shell,surface set reamer shell,tungsten carbide reamer shell,electroplated reaming shell.
