1. Tungsten Carbide Matric PDC Possesse high weqar resistance and impact resisitance. 2.Parabolic Crown profile and maximizes junk slot area can clean bit better, and prolong the bit working life. 3.Applying hydraulics balance design,5 renewal nozzles and reasonable nozzles locking angle can gain ideal fluid field in well bottom, fully clean and cool cutter, and prolong the cutter working life. 4. Non- symmetry blade arragement enhances drilling well balance. 5. Optimizaiton for cutter shape, slant angle, cutter numbers prolong the cutter working lift in combination withe high quality PDC cutter, and improve ROP and drilling efficiency. 6.It can be used on rotary or down hole motor. 7.High HIS is recommended. Product Advantages: 1. PDC cutters for high speed drilling; 2. All cutters are premium grade for extended bit life and durability; 3. Cutter layout is force balanced to drill a precise round hole and reduce bit whirl; 4. Large junk slots and flushing ports; 5. Advanced geometric design for faster penetration; 6. Gauge pads have tungsten carbide inserts for maximum wear resistance;
