Impregnated Diamond bit

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
4: The impregnated diamond core drill bits are of various configurations and meet various needs of local conditions
5: It offers the most widely-used bit matrices as well
6: With various specifications, our series matrix range provide an easy selection and reliable foundation for your drilling needs

Size: Our bits are available in all standard drilling sizes. Also, non-standard sized bits can be produced according to requirements from clients
Matrix height: 6mm-8mm (most cost-effective), 8mm-10mm (long service life), 12mm-16mm (super service life)
Bit Crown Profiles: “W” profile, “Flat” profile, “Semi-round” profile, “Cross” profile, “Gear profile”
Waterways: Various waterways are available for diamond impregnated bits. Differing waterways allow for better flushing in various ground conditions and drilling systems.
Threads: Standard Q threads as well as thread types required by clients are available
