How to find the right Industrial Metal Cutting Circular Saw Blades AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Industrial Metal Cutting Circular Saw Blades
- Ferrous vs non-ferrous
- Use a blade labelled for ferrous metal on steel. Use a non-ferrous blade, typically with a negative hook angle, on aluminum, copper and brass. The tooth geometry and carbide grade differ, and the wrong blade chips teeth or grabs the work.
- Teeth in the cut
- Keep at least three teeth in the material at once: higher tooth counts for thin wall and sheet, lower for solid bar and plate. Too few teeth engaged makes them snag and chip. Too many on thick stock packs the gullets with chips.
- RPM rating
- The blade's maximum RPM must be at or above the saw's no-load speed. An over-sped blade can fail, and dry-cut metal saws run slower than wood saws for this reason.
- Arbor and diameter match
- The blade's diameter and arbor bore must match the saw exactly. Use the saw maker's bushings only. An off-size bore causes runout and tooth breakage.
- Tooth material
- Cermet or carbide tips for dry-cut circular saws. Solid HSS or tipped cold-saw blades for low-RPM cold saws. Dry-cut and cold-saw blades are designed for very different surface speeds and are not interchangeable.
Brands that matter
- Diablo: Steel Demon and non-ferrous blades sized for portable and chop saws.
- Milwaukee: Metal-cutting blades matched to its cordless metal circular saws.
- Evolution: Multi-material and steel blades for its dry-cut saws.
- Lenox: Industrial metal-cutting blades and cold-saw blades.
- Makita: Metal-cutting blades for its own dry-cut saws.
- Morse: Metal Devil cermet-tipped dry-cut blades.
What to avoid
- Wood blades on metal
- Ferrous blades used on aluminum, or the reverse
- Blades with an RPM rating below the saw's speed
- Cutting stainless with a blade not rated for it
Questions
Can I put a metal blade in my wood circular saw?
Only if the blade's RPM rating covers the saw's speed and the saw has chip and guard protection for metal. Dedicated metal saws run slower and collect hot chips.
