What thickness of aluminum ?
The plate is 1/4 inch thick. Am I doing it wrong...? I am cramping the speed setting max and it is barely making a dent.That is just a Dremel knockoff. Given the proper cutting wheel, that should absolutely cut alu.
Unless, of course, you're trying to cut through 1" plate.
What are you actually trying to cut?
I am just trying to cut my aluminum plates to proper dimensions. The band saws are very expensive though...That is the important question. If you are trying to cut square stock then a band saw or cutoff saw. Holes in aluminum plate would best be a jigsaw. Use a drill to create an opening for the blade. It depends on what you are cutting.
Cutting 2021 was always a pain.A jigsaw will work with a good metal cutting blade. Also get a fairly coarse blade since the aluminum unlike other metals will actually melt and fill in the teeth on finer blades, making them useless after cutting a few inches (yeah I've tried it before). You'll also probably need more than one blade. A jigsaw like this is probably adequate.
