  • Product Detail

The impregnated diamond bitsare 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 bits’ matrix series. The matrix layer of the crown contains a uniform distribution of crystals that are embedded in a powdered metal bond. The matrix is designed to expose new diamonds to the bits' cutting face as wearing occurs. Fast penetration rate is maintained as a result of this action. The main technical parameters of bits are diamond specifications, like type, size, concentration and grade, as well as matrix hardness type and crown shapes, which are selected according to the hardness and abrasiveness of the formation to be drilled. If user can make rational selections according to the rock formations, then they can get satisfied drilling performance on various formations with different hardness.
