impregnated diamond core bits are the most commonly useful bits in the mineral exploration industry, as they have the widest range of application. The carefully selected grades of high quality synthetic diamond are distributed in the depth of impregnated bit's matrix series.

Surface set Diamond Core Bits are mostly suited to soft formations or using low powered drills, as they operate more effectively than impregnated bits at low surface speeds. Available with different stone sizes, face profiles and waterway arrangements to suit different conditions. All supplied with highest quality natural drilling diamonds.

Impregnated Diamond Core Bits can drill a broad range of formations from the softest to the hardest rocks. Manufactured with very small, high quality synthetic diamonds, mixed evenly through a metal alloy matrix. All bits have T.C. and Diamond gauge protection. Available in 6 standard matrix types to suit rock formation.

Matrix rated 7, core bits are manufactured using only the highest grade diamonds, which are coated with titanium in order to preserve their cutting abilities throughout the bit furnacing process. Furthermore, they are manufactured using a new unitary furnacing process regularizing the consistency of the tools.
