TSP(Thermally Stable Polycrystalline Diamond)

TSP diamond is made of diamond micro powder and a small amount of binder sintered under high temperature and high pressure. It has high wear resistance, strong impact toughness, good thermally stability, and dense structure, and is widely used in the manufacture of petroleum, geological drill bits, and Machining tools and gem processing.


Thermally Stable Polycrystalline Diamond (TSP) is also called polycrystalline diamond solid pieces. TSP consists of diamond powder & bonder and is made in an ultra-high pressure and high temperature. TSP features good thermally stability up to 1200°C, due to its thermally expansion binder the same as diamond and its chemical inertness.


Application: drilling bits and gauging.


We supply all types of TSP with various shapes and hardness.
