We can manufacture the diameter size up to 400mm impregnated core drill bits. Impregnated core bits can drill a broad range of geological formations from the softest to the hardest rock. They are manufactured with very small, high quality synthetic diamonds mixed evenly through a metal matrix. OZASIA impregnated drill bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum.
