Almost as important as the blade, aluminum cutting lube will make a significant difference.
In the olden days, they used a white stick that they would call “hog grease”, and it probably was as when my German Shepherd got a whiff of it he went crazy.
I think they use synthetics nowadays. But use something, it makes a difference.
I bought oshlun for my TS55 and a second for my Milwaukee M18 miter saw. They both worked great, but I just wanted affordable blades for a single project cutting 80-20 extrusions, aluminum sheets and plate stock.
