PDC Drill Bits

PDC Drill Bits

The main structure features:

n       Tungsten carbidematrix PDC possesses high wear resistance and impact resistance.

n       Parabolic crown profile and maximizes junk slot area can clean bit better, and prolong the bit working life.

n       Applying hydraulics balance design, 5 renewal nozzles and reasonable nozzles locating angle can gain ideal fluid field in well bottom, fully clean and cool cutter, and prolong the cutter working life.

n       Non-symmetry blade arrangement enhances drilling well balance.

n       Optimization for cutter shape, slant angle, cutter numbers prolong the cutter working life in combination with high quality PDC cutter, and improve ROP and drilling efficiency.

n       It can be used on rotary or down hole motor.

n       High HIS is recommended.
