Design character:

■Special blade structure increases adaptive ability of PDC bits in complicated rock formation greatly.

These cutters reduce torque of PDC bit, help to cut rocks, to keep stable in drilling.

With this design, pressure to PDC bit is balanced in drilling, and flow area is wide enough to make PDC bit perform well in

various formations.

■When drilling in mixture formation of sandstone, mudstone, glutenite, limestone, dolomite, halite, this type of PDC bit

perform well overall. Each bit can drill 500 to 800 meters depth.
