Tunnel boring projects have become increasingly critical in the construction industry, enabling the creation of underground passages for transportation systems, water pipelines, and even underground cities. These projects require sophisticated equipment, such as roller cone drill bits, to achieve efficient and accurate drilling. In this blog, we will delve into the significance of roller cone drill bits in tunnel boring projects and how they play a crucial role in shaping our future infrastructure.

The China tricone bit has the function of impacting, crushing and shearing and breaking the stratum rock when it rotates. Therefore, the tricone roller bit can adapt to various soft, medium and hard stratums. Especially after the emergence of jet-type tricone roller bits and long-nozzle tricone roller bits, the drilling speed of tricone roller bits has greatly increased, which is a major revolution in the history of the development of cone bits.
