Impregnent Rock Tools Drilling Equipments AQ BQ NQ HQ PQ Standard High Petration Rate
Impregnated Diamond Core Bits are manufactured with very small, high quality sythetic diamonds, mixed evenly through a metal alloy matrix. The matrix erodes away at the same rate as the diamonds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock. In most geological formations, impregnated bits are more economical to use than other bits.
Core Bits are used for drilling materials like the rock, concrete, limestone, granite, marble, clay, basalt, schist, quartz etc.
The bit mainly consists of diamond, steel body, carbide powder and polycrystalline diamond. The polycrystalline diamond is utilized to avoid too much abrasion of drill bits. The impregnated diamond is synthetic diamond (also called artificial diamond), which costs less but is more suitable to be used in drilling hard formations.
