With excellent hardness, outstanding wear resistance, and superior compressive strength, carbide rods are widely used in CNC machining, metal cutting, drilling, and high-precision tooling industries.
Our company specializes in the production of high-quality tungsten carbide rods made from ultra-fine tungsten carbide powder and cobalt binder, ensuring stable performance, long tool life, and consistent machining results.
We supply both solid carbide rods and coolant hole carbide rods (single hole / double straight holes / double helical holes) to meet different machining requirements ranging from general machining to high-speed and high-precision cutting applications.
2. Key Advantages of Our Tungsten Carbide Rods
(1) Exceptional Hardness and Wear Resistance
Our carbide rods achieve hardness levels up to HRA 92.5–93.5, making them suitable for cutting high-strength and abrasive materials such as stainless steel, cast iron, hardened steel, and alloy steel.
(2) High Transverse Rupture Strength (TRS)
Optimized cobalt content ensures excellent toughness and resistance to chipping or cracking during heavy-duty machining.
(3) Fine Grain Structure
We use ultra-fine grain powder technology, which significantly improves edge sharpness and tool life, especially for micro tools and precision cutting tools.
(4) Excellent Thermal Stability
Carbide rods maintain stable performance even under high-speed cutting conditions, reducing deformation and tool failure rate.
(5) Precision Grinding and Tight Tolerance
All ground rods are manufactured with strict dimensional control, ensuring consistency for tool makers and CNC manufacturers.
