rounded saw can it be used for.?
Good luckA circular saw is not the right tool for the job a sawzall or reciprocating saw would be betterBut since I am assuming you don't have one what you bought will have to doHold on tight and make sure you don't let the blade get pinchedWhen that happens is when most people lose there faceBe care full you can do just make sure you wear plenty of protection, there will be lots of flying aluminum (just remember that you can only cut through aluminum nothing else) A tight grip, and make sure the piece you are cutting is stable and will not move when you are cuttingEye protection is a must, long not loose sleeves are also a must as could be picking pieces of metal out of your arm for a week if you don't wear sleeves.
