Trait:double rows、7 spiral blades、7 water hole

Suitable for medium hard formations with high compressive strength and abrasiveness

Limestone、anhydrite、dolomite、mudstone…

Sintered with high-quality tungsten carbide material

Excellent erosion resistance

Structure of short parabola with spiral deep blade、anti-rotation design

Maximize the abrasion resistance and stability of bit
Increase the mechanical penetration rate and stability of the bit

Reasonable configuration of high-quality PDC cutters

Optimize the tooth distribution structure、increase the attack ability and wear resistance of the bit

Arc gauge

Reduce the wear of the gauge、increase the wear resistance and stability of the bit

Optimize water circulation system、increase the number of nozzles

Equilibrium fluid flow、reduce erosion bit、cooling cutting teeth
Design of bottom hole flow field、beneficial to the chips removal and the mud bags prevention
