·Adopting IDS equidistant design models
·Adopting C1, P1/P2, G2 crown types and high pressure type cutters to enhance single tooth axial load
·Implementing smooth cutting technology to prevent excessive torque that may lead to early damage of the drill bit or pump stalling
·Employing H1 hydraulic structure design to improve cuttings removal capacity
·Using T2, T3 high-performance cutters and small chamfer design technology to enhance penetrating capacity.
