Natural diamond dill bit
Natural diamond drill bit
Hard and consolidated formation drilling
Superior natural diamond grains are sintered on the erosion-resistant bit body. With urtral hard and optimized layout. natrual diamond bit can penetrate in hard and consolidated formations with medium abrasiveness and high compressive strength like the granite and quartz.
Various crown profiles
Natural diamond bits are designed with different crown profiles like parabolics. round or cone, with different diamond grain sizes and cutters layout, ehich can improve the cooling and cleaning of the surface and prolong service life.
