TSP is thermally stable polycrystalline diamond, a versatile material with the hardness of diamond, thermal stability up to 1200°C, and the ability to be manufactured into numerous shapes and sizes.

One of the primary applications for TSP is wear protection on the gage of drill bits, but in softer formations, it can be used as a primary cutting element, as well. Because of their performance properties, TSP can also be used in cutting tools, as dressers, as a die material for drawing wire, and for numerous other wear applications.

With our in-house testing lab, MoreSuperHard has done extensive research into the TSP materials on the market in order to ensure that we only supply TSP with the highest performance and the greatest value. Our proprietary slurry abrasion test evaluates the abrasive wear properties and toughness of the materials to determine which grades will provide you with the best overall performance. Our extensive in-house inventory ensures that we can provide you with the TSP you need when you need it.

Thermal Stable Polycrystalline diamond (TSP) 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.


TSP diamond for oil drill bits are suitable for oil mining fields, cutting tools, wire drawing dies etc. TSP diamond for oil drill bits It is achieved in an environment of high temperature and super high pressure and thermally stable up to 1,200°C for its insert binder (mainly Si). Its SiC has a similar coefficient of thermal expansion to that of diamond & enjoys very good wear-resistance.


Different thermally stable polycrystalline diamond products with different performances of wear-resistance, toughness, self-sharpening & high-temperature resistance can be used in gem-processing, Sic wheel dressers, wire drawing dies, coated cutters, etc. It can be applied on the drilling bits for oilfields.

Available Shapes:

Triangle, cube, cylinder, special shapes Available Sizes: 6.3*3.3, 1.5×1.5×1.5, 3×3×10, 5.5×5.5×4.5, 3×3×2.6, 8×8×4, 3×3×10×r1.5, 3×3×10×r2.5, 2×4×120...

Quality Control:

 1. Strict raw material selection to guarantee impurity below 200ppm; the binder's purity over 99.5%.

2. Advanced blending techniques to ensure thorough & even blending of diamond with binder.

3. Scientific formula & synthesis procedures. We can also adjust formula & procedures as per customers' requirements for the most suitable products.

4. Strict control of other auxiliary materials to guarantee precise dimensions & best quality.
