2. High drilling efficiency: the high grade hardness of the carbides can always stay sharp, which could increase the drilling speeds too;
3. New Diamond's bits are widely used in different rock formations like carbonate rock,limestone,chalk rock, clay rock,siltstone and sandstone;
4. It can greatly reduce the drilling cost, because of its high drilling speed and life span, which reduces the times to changes bits in the drilling service.
