·Adopting IDS equal wear design models
·Using C2, P1/P2, G2 crown types to optimize the internal cone bearing pressure and improve straight well anti-deviation capabilities
·Using T1, T2, T3 cutters to enhance nose overall performance and shoulder impact resistance
·Applying HI hydraulic structure design to improve cuttings transport speed and prevent mud cake
·Ensuring the balance force is within the green standard, combined with power drilling tools to enhance interlayer penetration capabilities.
