TSP - Thermally Stable Polycrystalline Diamond
Thermally Stable Polycrystalline (TSP) diamond can be manufactured into a variety of sizes and shapes (Cubes, Cylinders, Discs, Rectangles, Triangles, Spheres etc.) that can be inserted into cutting tools, drilling bits, reamers, wire drawing dies, and other wear-resistant components.
TSP mining and oil drilling bits are best suited for more abrasive or broken formations. Drill bits and reaming shells made with TSP diamonds 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.
One significant advantage of our TSP diamond is its high thermal stability. Our TSP Cutters can withstand high temperatures of ~1200 degrees centigrade in a non-oxidizing atmosphere. Moreover, the relative wear resistance of the TSP diamond body remains the same under high temperature conditions.
Because of these excellent properties, our TSP Cutters can be made into tools and other products by means of high-temperature brazing or high-temperature sintering.
Custom sizes, shapes, angles and coatings available.
