Please, get a deburring wheel, also called a sanding wheel. It's basically a non-ferrous grinding wheel. You will thank me later.

Should last a couple of seasons of reasonably heavy use.
Also as a side note, aluminum on a stone grinding wheel expands at a different rate when heated by friction and will eventually risk compromising the integrity of your wheel if not frequently dressed. Nobody wants 3000 rpm of stone to explode in their face.
