Custom carbide tool rods are high-performance components made from tungsten carbide (WC) as the hard phase and cobalt (Co) as the binder phase through precision powder metallurgy. They are widely used in woodworking, metal cutting, stone processing, road milling, and composite material drilling, providing a high-strength, high-wear-resistant substrate or working part for various cutting tools.

• Extremely High Hardness & Wear Resistance: Hardness up to HRA 88-94, wear life 5 to 20 times longer than high-speed steel (HSS)
• Excellent Transverse Rupture Strength (TRS): Typically 2000-3500 MPa, capable of withstanding high impact loads
• Good Red Hardness: Maintains high hardness and cutting performance at 800-1000°C
• Fully Customizable: Diameter, length, stepped shapes, holes, chamfers, coatings, etc., can be manufactured according to drawings
• High Dimensional Accuracy: Precision centerless or cylindrical grinding allows outer diameter tolerances as tight as ±0.002 mm

1. Woodworking Tools
   • Support rods or cutter bodies for finger joints, helical cutterheads, and planer blades
2. Metal Cutting
   • Micro-drills, reamers, milling cutter arbors, and positioning rods
3. Stone & Road Construction
   • Road milling picks/teeth and concrete breaking studs
4. Composites & High-Temperature Alloys
   • High-wear guide rods and turning tool blanks for heat-resistant alloys
5. Dies & Mechanical Parts
   • Wear-resistant core pins, punch rods, and locating pins

• Material analysis: Spectrometer / Carbon-sulfur analyzer
• Hardness testing: Rockwell hardness tester (HRA)
• Metallographic inspection: Porosity not exceeding A02B00
• Dimensional inspection: High-precision vision measuring machine / Laser micrometer
• Density testing: Archimedes method, accuracy ±0.02 g/cm³

Material certificates and dimensional inspection records are available for each batch.

• Machining hard materials (e.g., hardened steel, stone): Choose high-cobalt grades (e.g., YG10-YG15) for better impact resistance
• Extreme wear resistance (e.g., MDF, carbon fiber): Choose ultra-fine grain grades (e.g., YL10.2) with hardness ≥ HRA 92
• Dimensional fit requirements: Provide tolerances for mating holes/shafts, e.g., φ12h6 or φ10H7
• Rust prevention or reduced friction: Recommend TiAlN or diamond coating
