Sinodrills Diamond Core Bits

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.

SINODRILLS Impregnated Diamond Core Bits

The impregnated core bits are the tools cutting rock directly and they are usually applied for medium to ultra-hard formations. The bits’ crown is made up of metal power and diamond matrix which wears away during the drilling process and exposes new layers of diamond, renewing the cutting points. The combination of diamond and proprietary matrix result in the optimal performance.
