The impregnated diamond bits are the most commonly useful bits in the mineral exploration industry, as impregnated diamond bits 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 crown contains a uniform distribution of these crystals that are embedded in a powdered metal bond.
The matrix of our impregnated diamond 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 diamond bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum.
Our impregnated bit HQ3 NF3-4, used in a diamond core drilling project in Armenia, has broken a world record, for it drilled nine holes up to 1533.5 meters of depth and was used for periods up to 2 months. This geological exploration project, taken by Armenia Major Drilling Group, used our bits for drilling basalt (abrasive) sedimentary shale and siltstone (non-abrasive), whose hardness is medium to soft(Refer to Details).

Impregnated Diamond Bits

The optimum diamond size, concentration and matrix type are dependent on the hardness and abrasiveness of the formation to be drilled. When order, please read Matrix Selection Guide.
