Features
A. Threaded carbide rod with holes are mainly used for processing tungsten parts or as a tool bit of processing lathe, conductors, steel-making burdening and additives;
B. They are also applied in crankshaft, cylinder burdening and electrodes for advanced automobiles;
C. They are also produced as components for manufacturing of artillery, rockets, satellites, aircrafts and ships. In addition, helical coolant ducts can be also used as radiation-proof material in nuclear industry.
