Product Description

-PRODUCT BRIEF-

Brief Introductions of Impregnated Diamond Bits
The impregnated diamond bits are cutting tools. They contain diamond segments bonded to a base material. They are widely applied in cutting non-ferrous materials. The selected grades of synthetic diamond of high quality 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. This diamond tool is widely applied in the mineral exploration industry.

Features of Impregnated Diamond Bits
1. This diamond tool features with fast penetration rate, because the matrix of our impregnated diamond bits is specially designed (it is designed to expose new diamonds to the bits' cutting face as wear occurs).
2. Can help reduce the cost for diamond drilling: our impregnated diamond bits are manufactured to give optimum penetration rates and service life.
3. The hardness and abrasiveness of the formation to be drilled largely determined the optimum diamond size, concentration and matrix type, etc.
