NMLC Drilling bits for granite hard rock
Our 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 "DIYFIA" contains a uniform distribution of these crystal 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.
