Features and Applications 

Which is a matrix body PDC bit using arc--type double rows blades asymmertic design. Medium parabolic cutting structure design using the force blance ,helping to increase the stability of the PDC bit. High wear wide gauge design with different structure patent cutters are laid out at different location of the bit to ensure its high aggressiveness and long bit life .Effectively improve the rate of speed.Dynamic flow simulating technology is used for hydraulic design to ensure optimum bottom hole flow patters and anti-balling.

Medium hard to hard formations with  high compressive strength and abrasive ,such as Shale , Limestone ,Anhydrite , Sandstone and so on.
