Alloy multi tooth hard drill bit, coupled with an infinitely variable speed motor to drive the worm gear box, achieves precise fast and slow drilling and lifting. The 45, 55, and 75kw main motors drive the 145142153 gearbox to achieve high torque output, which has obvious requirements for easy drilling, uniform mixing, and pile forming in complex geological conditions.
