I have a six foot piece of aluminum angle "iron". The aluminum is 1/16" thick and the two wings are 1 1/2". I want to cut some 2" pieces to use as brackets for a support beam. I want the cuts to be square, smooth and even so using a hand held hack saw is not an option. How can I cut this angle iron? Is it possible and safe to use a carbide tipped saw blade on a miter saw? Any advice or help would be appreciated.
