it comes to tungsten carbide blades（TC blades）, selecting the right material composition and blade type is crucial depending on the intended use. Here’s a quick guide to help you understand what tungsten carbide is, its benefits, and how to choose the right blade for your application:
What is Tungsten Carbide?
Tungsten carbide is a composite material made of tungsten and carbon atoms. It’s extremely hard and wear-resistant, ranking about 9 on the Mohs scale (just below diamond). The material is often bonded with cobalt or other binders to enhance toughness.
Key Benefits of Tungsten Carbide Blades（TC Blades）
Exceptional hardness – maintains a sharp edge longer than steel
High wear resistance – ideal for abrasive or tough materials
Thermal resistance – can handle high-speed cutting without degrading
Corrosion resistance – holds up well in various environments
Choosing the Right Tungsten Carbide Blade（TC blades）
1.Application Type
Woodworking: Choose micro-grain carbide-tipped blades for clean, precise cuts.
Metal cutting: Use solid carbide or brazed-tip blades, especially for non-ferrous metals.
Plastic/Fiberglass: Go for blades with polished teeth to reduce friction and melting.
Paper/Textiles: Opt for fine-toothed or razor-sharp circular carbide blades.
2.Blade Geometry
Tooth shape and count: More teeth = smoother cut. Alternate top bevel (ATB) is common for woodworking.
Gullet size: Bigger gullets help with faster chip removal, useful in ripping operations.
3.Grade of Carbide
C1 to C4 grades (ISO): Lower numbers = harder (C1), higher numbers = tougher (C4).
C2/C3: Good for general-purpose cutting.
C4: Excellent for high-impact jobs but slightly less wear-resistant.
4.Binder Content
Higher cobalt = more toughness, less wear resistance.
Lower cobalt = harder, more brittle, but stays sharp longer.
Pro Tips
Regularly inspect and sharpen the blades to extend life.
Match the RPM rating of the blade with your tool for safety and performance.
Use proper coolant or lubrication when cutting metals.
