What Are Circular Saw Blades?
Circular saw blades come in a variety of materials and designs, each optimised for cutting different materials and compositions. Whether you're working with wood, metal, plastic or composites, the right blade can mean the difference between clean cuts and costly downtime.

TCT Blades (Tungsten Carbide Tipped)
TCT blades feature tungsten carbide tips brazed onto a steel body, combining carbide's hardness with steel's toughness. They can operate at higher speeds and temperatures than HSS blades, making them ideal for faster cuts in a variety of materials.
Features:
• Extended lifespan: Retains sharpness far longer than HSS;
• Versatility: Effective on wood, plastics, composites and softer metals;
• High cutting speeds: Reduced cycle times boost productivity.
Applications:
• General-purpose woodworking;
• Plastic and composite cutting;
• Non-ferrous metal cutting;
• Fast-feed production environments.
HSS Blades (High-Speed Steel)
HSS blades are made entirely from high-speed steel, prized for its hardness and heat resistance. They can be resharpened multiple times and maintain a clean cutting edge.
Features:
- Clean, precise cuts especially in hardwoods and non-ferrous metals;
- Lower cost than carbide or diamond tipped blades;
- Ease of sharpening extends useful life with minimal equipment.
Applications:
- Fine woodworking and cabinetry;
- Metal filing or trimming;
- Light-duty production where budget constraints exist.
PCD Blades (Polycrystalline Diamond)
PCD blades have cutting edges made from synthetic diamond particles sintered into a carbide substrate. This imparts extreme hardness and wear resistance.
Features:
• Unmatched wear life: Up to 50× the service life of carbide blades;
• Exceptional edge retention: Ideal for abrasive or hard materials;
• Service multiple times for extended use.
Applications:
• Composite decking and fibre cement board;
• High-pressure laminate (HPL) and melamine panels;
• Fiberglass, plastics and ultra-precision woodworking;
• Aerospace composites and carbon-fiber reinforced polymer (CFRP).
