Zhuzhou Century Tool manufactures premium Coolant Hole Tungsten Carbide Rods designed for high-speed and high-efficiency cutting tool production. These rods feature precision-engineered internal coolant channels that significantly improve heat dissipation, chip evacuation, and tool life during demanding CNC machining operations.
Produced from ultra-fine grain tungsten carbide powder using advanced HIP sintering technology, our coolant hole carbide rods offer excellent hardness, superior wear resistance, and outstanding fracture toughness. They are widely used for manufacturing high-performance Tungsten Carbide End Mills, Carbide Drills, and Reamers for steel, stainless steel, and hardened materials up to HRC 65.
The precision-drilled coolant holes allow cutting fluid to reach the cutting edge directly, effectively reducing cutting temperature and improving chip removal efficiency during high-speed machining.
Manufactured from high-quality Tungsten Carbide Rods base material, ensuring excellent hardness, wear resistance, and long tool life in demanding cutting environments.
Internal cooling significantly reduces thermal stress on cutting tools, extending tool life and improving machining stability during continuous production.
Advanced extrusion, sintering, and centerless grinding processes ensure excellent straightness, dimensional accuracy, and consistent quality for CNC tool production.
