1. The drill bit adopts a medium contour optimized design, which is suitable for soft to medium stratum.

　　2. Cutting structure force balance design, asymmetric blade design, spiral blade design, spiral gauge design, so that the drill bit is balanced in force and has better stability.

　　3. The high-performance composite sheet is used in combination to increase the life of the drill bit.

　　4. The shock-absorbing tooth design enables the drill bit to pass through part of the hard interlayer stratum.

　　 5. Adopt dynamic flow field simulation technology, optimize the hydraulic design of the drill bit, enhance the cleaning and cooling capacity of the drill bit, and prevent the bit mud pack.

　　6. The use of high erosion resistance surfacing materials and advanced substrate surface strengthening technology to prevent erosion of the surface of the drill bit.

　　7. Optimize the water hole design to prevent erosion of the runner in the drill bit.
