Five-blade wing-shaped tooth drill bit design, suitable for high-hardness impact formations. Secondary cutting teeth added to the rear row enhance cutting capacity. Triple-edge teeth near the diameter-preserving section improve lateral impact resistance in heterogeneous formations. Hydraulic design optimized via CFD employs a 7-water-eye rock-clearing structure that reduces mud packing while utilizing hydraulic jets to assist rock breaking.
