Best Circular Saw Blade for Cutting Corrugated Metal Review

Choosing the right circular saw blade for cutting corrugated metal is crucial for clean, efficient cuts and extended blade life. Corrugated metal, with its ribbed profile, presents unique challenges for saw blades. Here’s a review of some of the best options on the market, considering factors like tooth count, material, and design features.

Thin Kerf Blades: Thin kerf blades minimize material waste and reduce cutting resistance. Popular options include Freud Diablo Steel Demon and Lenox TriMaster Metal Cutting blades. These blades feature high-tooth counts (over 80 teeth) for smooth cuts.

Bi-Metal Blades: Bi-metal blades combine a high-speed steel (HSS) cutting edge with a flexible steel body. This design offers durability for cutting through tough materials like corrugated metal. Bosch Metal Max and Dewalt Bi-Metal Demolition blades are well-regarded choices in this category.

Triple Chip Grind (TCG) Blades: TCG blades feature teeth with three cutting angles, resulting in clean cuts with minimal burrs. Irwin Maraton Metal Demon and Milwaukee The AX Metal Mud Demon blades are examples of TCG blades that excel at cutting corrugated metal.

Abrasive Discs: Abrasive discs, also known as cut-off wheels, are ideal for straight cuts in corrugated metal. They are not recommended for curved cuts as they can cause significant material wear. Popular choices include Diablo Steel Demon Abrasive Blade and Dewalt Abrasive Cut-Off Disc.

Factors to Consider:

Thickness of Corrugated Metal: Choose a blade with a tooth count appropriate for the metal thickness. Higher tooth counts are better for thinner sheets.

Cut Quality: For clean, finished cuts, prioritize blades with high tooth counts and TCG designs.

Cutting Speed: Abrasive discs offer the fastest cutting speeds, while high tooth count blades prioritize cut quality over speed.

Conclusion

The best circular saw blade for cutting corrugated metal depends on your specific needs. Consider the thickness of the metal, desired cut quality, and cutting speed when making your choice. By selecting the right blade, you can ensure clean, efficient cuts and maximize the lifespan of your saw blade.
