The main structure features:
Tungsten carbide matrix PDC possesses high wear resistance and impact resistance.
Parabolic crown profile and maximises junk slot area can clean bit better, and prolong the bit working life.
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.
Non-symmetry blade arrangement enhances drilling well balance.
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.
It can be used on rotary or down hole motor
