A special double-row cutter coring bit suitable for coring operations in hard formations. The high-quality composite discs effectively enhance bit performance and service life. The cutting structure is highly aggressive, and large cuttings can be rapidly transported through optimized flow channels, preventing cuttings from blocking the annular flow channels.

The cutting structure is highly aggressive, and large cuttings can be rapidly transported through optimized flow channels, preventing cuttings from blocking the annular flow channels.
The force-balanced design makes the bit more stable during coring, resulting in more regular cores.
The gauge and inner cone are inset with high-strength TSP, greatly improving the bit's wear resistance and service life.
The special blade nozzle layout enhances the bit's cooling and cleaning capabilities and improves cuttings transport efficiency.
This coring bit achieves a high rate of penetration and long service life during operation, and the high-strength PDC cutters can complete coring operations in hard formations.
Customers can select different types of composite discs according to the hardness and abrasiveness of the formation being cored.
Advantages
High rate of penetration
Long service life
Good thermal stability
