It uses a 5/8″ arbor and is compatible with standard circular and trim saws.
Buying Guide: Key Purchase Considerations
- Material compatibility: Choose blades designed for ferrous metals (steel, iron) and consider whether you need non-ferrous versatility for aluminum and plastics.
- Tooth design and count: Higher tooth counts provide smoother cuts but may cut slower; lower tooth counts cut faster and aggressively for rough cuts on metal sections.
- Coatings and anti-stick features: coatings like TA or Cermet II reduce heat buildup and chip sticking, improving surface finish and blade life.
- Arbor size and kerf: Ensure the blade’s arbor (commonly 5/8″ or 20 mm) matches your saw; kerf width affects material removal and cut accuracy.
- RPM rating: Match the blade’s rated RPM to your saw’s speed to avoid overheating and ensure optimal performance.
- Durability and life: Carbide-tipped and cermet blades generally offer longer life in metal cutting; look for reduced downtime and fewer blade changes.
- Application scope: If you cut mixed materials, look for versatile options; for dedicated ferrous metal work, prioritize metal-specific teeth and coatings.
- Brand and warranty: Reputable brands with clear warranty support help protect your investment in professional settings.
