Designed for optimal cooling and chip evacuation, CYC's rods with helical coolant holes are perfect for high-speed cutting and drilling operations. These rods enhance tool life by reducing thermal stress during machining, ensuring greater precision and efficiency. Available in various configurations, they provide exceptional performance for deep hole drilling and other demanding applications.
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;
They are also applied in crankshaft, cylinder burdening and electrodes for advanced automobiles;
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.
