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.

Product Advantage:

1. Impregnated Diamond Bit: Special mental coated diamonds to extend the diamond working life.

2. Surface Set Diamond Bit: Choose natural diamond with the fast drilling speed, espencially used for soft, abrasive and unconsolidated rock formation.

3. Matrix Height: 7mm-25mm, provide better drilling speed and drilling life.

4. Drill Bit Design: Standard V-ring,Turbo, Face discharge, Flat face, Stepped, Vortex type,Pilot type, etc.
