I am looking for info on a 10″ miter saw blade. I cut a lot of aluminum and I need a clean cut with little spurs. can you advise the best teeth count to get?
It’s not just about tooth count. For cutting aluminum, your best bet would be for a blade suited for non-ferrous materials. These blades typically have “TCG” triple chip grind tooth profiles, which work best on aluminum and plastic materials.
Something like the Freud LU77M010 (more info, $62 via Amazon) is what I’d pick. This blade is designed for cutting non-ferrous tubing, plates, and profiles with 1/4″ maximum wall thicknesses, and there are other blades designed for cutting thicker and thinner aluminum materials.
Generally, non-ferrous TCG 10″ blades will have between 72 and 100 teeth.
Although I didn’t mention this to Susan, there are ways to cut aluminum materials with blades designed to cut wood. However, that’s not something I would recommend.
Years ago I purchased a now-discontinued Freud TK706 non-ferrous blade, and it’s served me quite well. I do have a small Evolution metal-cutting chop saw (here are some general opinions of the brand), but continue to use my Freud blade for certain things.
Freud and Diablo are my preferred miter saw blade brands, but I would trust Oshlun too as a 3rd brand choice.
