Type 28 Diamond Composite Drill Bit

Detail

Diamond composite anchor drill bits are mainly used for drilling anchor support holes in coal mines. When used with hydraulic anchor drill rigs, they can greatly improve the drilling efficiency of hard rock formations, the stability of opening holes and the drilling process. The drill bit has a long life, is not easy to shrink, has a high hole formation rate, greatly reduces the waste of anchoring agents, anchor rods, and steel strands, improves construction efficiency, and reduces the labor intensity of workers. It is widely applicable to rock with a hardness of f≤12, which provides a strong guarantee for coal mine tunnel excavation.
