2 helical coolant holes carbide rod
Carbide rods featuring two helical coolant holes are designed to significantly reduce the wear and failure of tungsten carbide tools during high-speed machining. The coolant flowing through the helical holes helps maintain an even temperature, making these rods ideal for cutting and machining applications. The helix angle plays a vital role in chip evacuation efficiency, which is essential for minimizing tool wear and protecting the workpiece.
As a reliable carbide rod China supplier, we offer options with 30° and 40° helix angles, available in both unground and ground forms across various grades. To learn more about our carbide grades, please follow the link below to access our detailed grade page.
You can find a comprehensive selection of carbide rods with helical coolant holes in various dimensions listed in the tables below. We also welcome requests for custom sizes, tolerances, and configurations to meet your specific requirements.
