Tungsten Carbide Cutting Discs
Key Features & Benefits
Ultra-high hardness and wear resistance
Tungsten carbide (hardness HV~2200) far exceeds ordinary abrasives (such as aluminum oxide, silicon carbide) and can cut:
- High-hardness metals such as hardened steel, tool steel, and alloy steel;
- Wear-resistant materials such as cast iron and stainless steel;
- Non-metallic hard materials such as composite materials, ceramics, and stone.
Significantly extended life
The cutting edge remains sharp several times longer than traditional grinding wheels, reducing the frequency of replacement and long-term costs.
Efficient cutting and precision
Quickly remove materials while reducing thermal deformation (correct operation required);
Smoother cuts and fewer burrs, suitable for precision processing needs.
Multi-functional adaptation
Pure tungsten carbide cutting disc: powerful cutting for metals and alloys;
Diamond composite (tungsten carbide + diamond particles): used for ultra-hard building materials such as concrete and asphalt.

Frequently Asked Question(FAQ)
Q: Is it normal to have sparks when cutting?
A: A small amount of sparks is normal, but if it is significantly larger than normal, you should stop the machine immediately for inspection.
Q: How does a tungsten carbide cutting disc compare to a standard abrasive disc?
A: Standard discs (e.g., aluminum oxide or silicon carbide) are softer and wear out quickly on hard metals. Tungsten carbide discs last 3–5x longer and provide cleaner cuts.
Q: How do you determine if it needs to be replaced?
A: When the cutting time is extended by 50% or obvious vibration occurs, it should be replaced.
Conclusion
Tungsten carbide cutting discs are ideal for heavy industry, construction and high-end processing, especially for high wear resistance and high load scenarios where traditional grinding wheels are not competent.
