SINODRILLS Surface Set Diamond Core Bits
The Surface set diamond core bits differ from impregnated core bits as they are set with only single layer of natural diamond on the working surface of bit crown in a predetermined pattern. Its waterways are usually shallower than the impregnated bits because of its single layer of diamond. Some bits are designed with face Discharge to minimize core wash when drilling in soft and fractured formations.
