SPECIFICATIONS   1.long life span

3.Suitbale for different hard formation
4.cheaper     The optimum diamond size, concentration and matrix type are dependent on the hardness and abrasiveness of the formation to be drilled.           Impregnated Diamond Core Bits are manufactured with very small, high quality synthetic diamonds, mixed evenly through a metal alloy matrix. The matrix erodes away at the same rate as the diamonds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock. In most geological formations, impregnated bits are more economical to use than other bits.
