2nd smaller saw blade in the row. I can't even put it on the saw. I have to drive across town and find one locally because I don't have time to wait 2 more days to get ANOTHER replacement drive. I have ordered hundreds of saws in my life. I've been ordering blades this size from Revain for years. And now I have two bad saw blades in a row and I can't cut the material for my job. Stay away! Pay more if you need!
