Blades for circular saws

To choose blades for circular saws, start by identifying your main material and cut type. For wood, pick a carbide-tipped blade from trusted brands like Total or Irwin, with enough teeth for a smooth finish. Check the blade size and arbor compatibility with your saw, and confirm the maximum RPM matches. Choose tooth geometry based on the cut: more teeth for clean crosscuts, fewer teeth for fast, rough ripping.

Tooth geometry and count drive finish quality and cutting speed. More teeth mean a smoother cut but slower feed; fewer teeth clear material faster and handle tougher work. For fine plywood or hardwood, look for higher tooth counts and carbide tips; for quick ripping or metal, a blade with fewer teeth and a robust grind works better. Carbide-tipped teeth from brands like Milwaukee or Irwin provide durability for frequent use.

Beginners should start with a versatile carbide-tipped wood blade that offers predictable results and good durability. Pros may select specialized blades: metal-cutting carbide blades for metal tasks, or high-precision wood blades for flawless finishes. Always match the blade diameter and kerf to your saw and the task, using trusted brands like Hitachi, Total, or Irwin for dependable performance.

Mount the blade only after unplugging the saw and ensure the arbor size matches the blade. Securely tighten the nut or flange and verify the blade spins true before cutting. After use, clean resin and debris, inspect for chipped teeth or cracks, and store blades in a safe container. Use guards and follow the manufacturer’s safety guidelines for maximum RPM and material compatibility.

For wood, choose carbide-tipped wood blades from brands like Total or Irwin for clean cuts. For metal, use metal-cutting circular blades with carbide teeth from reliable brands, ensuring your saw is approved for metal work. Avoid using wood blades on metal and mismatched blades on unfamiliar materials; always select a blade designed for the target material and check the saw’s compatibility.

Replace blades when teeth are dull, chipped, or burns appear on the cut, or if the kerf widens unevenly. Inspect for warping, cracks, or looseness in the arbor fit. Follow the blade maker’s guidelines for max RPM and material compatibility, and choose brands with proven durability like Milwaukee, Irwin, or Total to maintain safe, precise cutting.
