You should be fine at the 3000rpm limit of the Grizzly G1006 in cutting most any Aluminum, look for aluminum cutting carbide cutters, I began using 3 flute some time back and really like them, MSC sells them, Accupro 3 Flute 50 degree helix, for aluminum. More expensive then standard carbide but worth it in my opinion. Also checkout Discount Tools, they have a good selection of cutters at really good prices. With flood coolant in aluminum it is more about flushing the chips away from the cutter then cooling or lubricant.
