Review on Denali 7-1/4 Inch 68 Tooth Metal Cutting Circular Saw Blade - 5/8 Inch Arbor | Amazon Brand by Jamar Gow

This is a nice option for cutting thin ferrous metals, but only if you don't have the budget or space for metal-working specific tools. Usually, you need a slower speed to cut ferrous metals perfectly than is available on a circular saw, and that is mostly because of the blade and work piece heating up too much, as I understand it. That said, this blade does have a unique and specific tooth pattern unlike any of your wood or non-ferrous metal blades and that pattern is clean and nice and I believe proper carbide. For best results, I'd clamp your sheet metal down to some disposable wood so you don't have to worry about bending and warping of the work piece.A bit of a niche product, but the blade seems to be excellent quality. 5 stars if you're just not interested in buying metal-specific tools on top of just the blades.
