·Adopting IDS equidistant design models
·Using C3, P3/P4, G2/G3 crown types to strengthen the internal cone and shoulder tooth density, preventing wellbore contraction
·Using T4, T5 high-performance cutters to enhance wear resistance
·Applying H2 hydraulic structure design to improve tooth surface cooling effect
·Implementing multi-blade design technology
·Implementing B13, BA auxiliary design to improve drill stability and shoulder wear resistance.
