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, natural 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, which can improve the cooling and cleaning of the surface and prolong service life.
