The Ultimate Solution for High-Performance Industrial Applications

What are the advantages of KOIHO’s Tungsten Carbide Rods?

1. Unmatched Hardness & Wear Resistance

KOIHO’s solid tungsten carbide rods (HRC 70-75) outperform competitors in brutal working conditions. Our proprietary sintering technology creates a dense, pore-free microstructure that resists:

• Abrasive wear in rock drilling and mining operations

• Thermal deformation in high-speed machining (up to 1,200°C)

• Corrosion in chemical processing environments

Featured Product: High-Hardness Carbide Solid Round Bar

2. Precision Engineering for Critical Applications

Achieve micron-level accuracy with our polished carbide rods, available in diameters from 1mm to 50mm. Key features include:

• H6-grade dimensional tolerance (±0.002mm) for CNC tooling

• Mirror-like surface finish (Ra ≤0.1μm) to reduce friction

• Custom lengths up to 500mm for specialized machinery

3. Versatility Across Industries

From aerospace to oil & gas, KOIHO’s cemented carbide bars serve as the backbone of mission-critical components:
✅ Mining & Drilling: Rock drill bits, button bits
✅ Manufacturing: End mills, inserts, punches
✅ Energy: Valve seats, nozzles, bearings
✅ Automotive: Wear plates, forming dies

Technical Excellence That Delivers ROI

Our YL10.2 ground carbide rods are engineered to maximize operational efficiency:

• 30% higher productivity: Reduced tool change frequency
