  • Optimum Design - PDC BIT/TRICONE BIT/DRILL BITS

    The results show that the drilli ability is grade 1 to 6, hardness is 169-733 Mpa, formation is soft to medium. Adopting design with 4 wings, deep inner cone, low density cutters placement, using CFD to optimize hydraulic structure of PDC bits, we designed out a PDC bit 9 1/2’’WS416DR with good effective.
