PDC core bit selection of high-quality diamond composite sheet, with high wear resistance, high drilling efficiency, not easy to reduce diameter, constant quality characteristics, greatly improve the drilling efficiency, can improve the construction efficiency, reduce construction labor

F=10, the best effect in the use of rock. It is mainly used for drilling in geological exploration and hydrologic exploration.
