Symmetrical parabola crown profile,asymmetrical bit blades ,the cutters are distributed as the curve and the gauge is designed spiral so that the stability of the bit is encouraged.Besides that the edge of gauge is enhanced by extra cutters. The flow roomage is optimal designed so that the mud and rock granule can be clear easily in drilling.
2.High wear resistance cutters.High performance PDC cutters optimal designed highly increased the efficiency of drilling.
3.Oppose-circumnutation designed.The load on bit is balanced,and the journal libration is decreased as well as the stabilization of directional drilling is enhanced.
4.This type of bits are suitable for medium to hard formation.
