    Product Description

    Impregnated Diamond Core Bits are manufactured with very small, high quality sythetic 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.
