The alumium even impacts itself into the teeth of a carbide burr on a air powered die grinder. You have to continually stop and clean the cutter with a scribe.
yeah, I know, I end up using manual methods for my work to avoid that, I've got a decent assortment of files in my box, along with a file brush... it doesn't take much to cut through aluminum, but if you try to go too fast you'll end up taking longer... I do wish I had a blade for my bandsaw though...
