Is it ok to countersink steel with the cutter used for aluminum? If so, is d done differently? Maybe turn slower and use lube?
 
You got it. It will work well if you keep the speed down and the cutter relatively cool, but it will still dull much faster than cutting 2024T3.
 
I put the cutter in my trusty DeWalt set to "low" and leave the air tools aside for cutting steel. A bit 'o Boelube works nicely.
