·Adopting IDS equal wear design models
Using C1, P1/P2, G1 crown types and segmented gauge retention design technology to improve drill bit guidance
·Employing low torque design technology and micro-spiral gauge retention design technology to ensure balance force within the green standard and enhance tool face stability
·Adopting dual crown design for shoulder and gauge to improve drill bit lateral cutting capability
·Utilizing T3, T4 high-performance cutters to enhance overall performance
