60-120 precision drilling series drill bits

This 60-120 specification three-edge drill bit is mainly used for drilling in the soil layer section of medium-sized pile foundations and the shallow soil layer of deep water Wells. Its advantages focus on "dual optimization of cutting and slag removal + efficiency improvement + process connection and adaptation", precisely addressing the pain point of low drilling efficiency in thick clay and medium-dense sand layers, and accelerating small and medium-sized infrastructure projects. Its key performance has been deeply optimized: the cutting area and the slag discharge channel have been upgraded simultaneously. It can quickly break the soil layer structure when facing thick clay and also reduce resistance when drilling into medium-dense sand layers. At the same time, the optimized slag discharge channel accelerates the removal of soil debris, avoids the shutdown caused by the accumulation in the hole, and significantly improves the drilling efficiency. In addition, the durability is en…
