impregnated diamond bits are the most commonly useful bits in the mineral exploration industry, Protects the diamond from oxidation and surface degradation during producing.

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 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 using life, which is make the cost of diamond drilling to a minimum. And save driller working time.the driller not waste time on hoist out the drill rod to change the diamond core bit frequent.

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