The 60-140 three-edge drill bit is a core tool specially designed for "deep + large diameter" soft foundation drilling. It is mainly suitable for two scenarios: large-scale building foundation soil layer holes and long-distance municipal pipeline soil layer section construction. It precisely addresses the core pain points of low drilling efficiency and easy clogging inside the hole in deep soft soil layers.

Its key performance is enhanced around the requirements of deep hole operations: The three-edge cutting edge is made of highly wear-resistant material, which can withstand long-term continuous cutting in deep soil layers, reducing drill bit wear and replacement frequency, and avoiding frequent shutdowns that affect progress. The depth and width of the slag discharge trough have been well designed to quickly discharge the large amount of soil debris generated during deep hole drilling, eliminating the blockage inside the hole from the source and ensuring the continuous and stable drilling.

In practical scenarios, the value of this drill bit is particularly prominent: for the foundations of large commercial buildings in the urban core area - in such scenarios where the soil layer is thick and the structure is complex, it can efficiently penetrate deep and soft soil layers, creating regular tunnels for subsequent pile foundation rock penetration and ensuring that the load-bearing performance of the pile foundation meets the standards. When used in the construction of long-distance municipal pipe networks (such as the soil layer holes in the early stage of urban underground utility tunnels), it can stably ensure the continuity of the borehole and the stability of the hole wall, reduce the obstacles during pipeline laying, and provide strong support for the efficient advancement of large-scale soft foundation projects.
