HWL3 (HQ3) Impregnated Diamond Core Drill Bits With High Drilling
The 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. The matrix layer of the crown contains a uniform
distribution of these crystals that are embedded in a powdered
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
