Polycrystalline Diamond is a diamond combo produced by diamond sintered with bond under high temperature and high pressure; it has very high wearability and high thermal stability. TSP is an unbacked polycrystalline diamond product,which is manufactured by the same ultra-high pressure and high temperature techniques as other PCD products.It is thermally stable up to 1200 degree for its binder is chemically insert and has a similar coefficient of thermal expansion like that of diamond.

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.

All kinds of specifications are available upon your needs.
