With ISO certificate & quality control.

The impregnated diamond 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. The matrix layer of the ZM contains a uniform distribution of these crystals that are embedded in a powdered metal bond.

The matrix of our impregnated bits is designed to expose new diamonds to the bits' cutting face as wear occurs. Fast penetration rate is maintained as a result of this action.

Our impregnated bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum.

The optimum diamond size, concentration and matrix type are dependent on the hardness and abrasiveness of the formation to be drilled.
