Specification :

TSP series 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. 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. It is thermally stable up to 1200¡ãC for its binder is chemically inert and has a similiar coefficient of thermal expansion to that of diamond. It is suitable for mining bits and oil drlling bits.
