deasign features of PDC Oil Drill Bits
1.The design of the blade widens the flow channel of the drill bit,effectively prevents mud clogging,and the asymmetrical blade layout reduces the wear of cutting teeth.
2.This design provides the drill bit with a stronger attack drilling speed,bringing users a more efficient drilling experience.
3.We have adopted an anti-rotation design to enhance the stability of the blade and increase the drilling speed.
