Why do manufactures distinguish whether a blade is for a circular saw or miter saw? Is there difference that I'm not seeing?
One of the reasons I'm asking this is that I'm determining the safest way to cut aluminum while not ruining the tool or consumable. It seems the only blade designed for metal cutting available at my local big box store is a segmented diamond blade LENOX METALMAX 1972924. The diameter, arbor hole, kerf or max speed parameters should work for my DeWalt 7-1/4" miter saw. The biggest risk seems to be the lack of protection on the lower guard given a 1/4" blade diameter difference, which seems like a marginal risk since it seems designed for circular saw.
I know carbide blades, likely the more teeth the better should work as detailed in this question, nevertheless I'm looking for the best option, not one that will work.
