They are manufactured with high quality synthetic diamonds mixed evenly through a tungsten carbide matrix. (During drilling the matrix wears away evenly resulting in continuous exposure of new, sharp diamond points throughout the life of the bit.)
Diamond Reaming Shells are important tools to be used together with bits.Its main functions are 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.The matrix is wearproof,and its service life is long.
