Have used this blade a bit now. So far, so good. I mainly cut aluminium, but I cut steel with no problem, even a few cuts in tool steel. This is by far the smoothest blade seam I've ever had. It's almost invisible! I have 2 SuperCuts that failed during low mileage welding, one of them was welded crooked from the start. I hope all of their blades are just as good because I will be buying more. UPDATE 4/6/21 I just finally replaced this blade with the same blade. This blade is as smooth as the previous one. The saw is not used every day, but the house saw has come in handy on many projects. The blade eventually began to break, but not the weld. He lost a few teeth from shortening small rods or maybe a stainless steel exhaust pipe, so that doesn't help at all. I still say it's better than any Super Cuts I've had in the past and I will continue to buy them. .
