Circular Saw Blades (Sizes: 355-450mm)

These blades are designed for cut off saws and chop saws used to cut metal and masonry.  Abrasive discs or carbide tipped versions are available depending on the material.

What are large-diameter circular saw blades used for?
Blades in the 355 mm to 450 mm range are designed for high-capacity, industrial-grade cutting. They’re typically used on:

• Cut-off saws, industrial table saws, panel saws, and radial arm saws

• Applications involving timber beams, large sheet materials, aluminum profiles, and structural steel (with dry-cut blades)
  These blades are ideal for construction sites, sawmills, fabrication shops, and any job requiring deep or wide cuts.

What factors should I consider when selecting a large saw blade?

• Blade diameter – confirm your saw can safely accommodate the blade size

• Bore size – typically 25.4 mm (1") or 30 mm, sometimes with keyways or reducer bushings

• Tooth count –

  • 60T–80T for rougher crosscuts

  • 100T–120T+ for fine, clean cuts in wood or laminate panels

• Tooth material and geometry –

  • TCG (Triple Chip Grind) or carbide-tipped for durability

  • High ATB for laminated or veneered panels

  • Specialized dry-cut blades for steel, aluminum, and PVC

What safety and maintenance tips apply to blades in this size range?

• Always use the correct RPM rating for the blade and saw (larger blades require lower RPMs)

• Ensure the blade is balanced and undamaged—wobble can be dangerous at high speeds

• Clean the blade regularly and check for pitch buildup or damaged teeth

• Replace blades showing burning, vibration, or visible wear to maintain cut quality and operator safety
