Impregnated diamond bit
Product Description
The impregnated diamond 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 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.
The matrix layer of the impregnated diamond core drill bits crown contains a uniform distribution of these crystal diamonds that are embedded in a powdered metal bond. The main technical parameters of impregnated diamond core drill 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.
Features
1: the impregnated diamond core bits features drilling speed and long service life
2: the design of more cutting edges makes drilling progress smoother
3: during the manufacturing process, the diamond is free erosion and fully utilized
