| Polycrystalline diamond (PCD) aso call TSP (Thermal stable polycrystalline diamond),the thermal stable polycrystalline diamond is diamond polycrystalline products produced by sintering together selected synthetic diamond with a metal matrix using very sophisticated high-temperature and high-pressure technology. |
|
|
| The TSP (thermal stable polycrystalline) diamond can be manufactured into a variety of sizes and shapes (Cubes, Cylinders, Discs, Rectangles, Triangles, Spheres etc.) ,it can be inserted into PCD cutting tools, PCD drilling bits/core bits, reamers, PCD wire drawing dies, and other wear-resistant components. |
|
| TSP/PCD mining and oil drilling bits are best suited for more abrasive or broken formations. TSP/PCD diamond drill bits and are suitable for drilling in soft rocks with hardness below 7 degrees, such as lime rock, marble, shale, etc; and in medium to hard rocks with coarse grains, such as sedimentary rock. The results obtained in drilling medium to hard rocks and non-uniform abrasive formations are much better than those obtained with drill bits impregnated or surface-set with single, natural diamond crystals. |
