Diamond Reaming Shell are important tools to be used together with bits. It's main fuctions are maintaining borehole gauge. 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 the working life is long.
