Ron,
That's great that you got that deal on cutter with inserts. Quite a good bargain, for sure.
The ODHT0504ZZN-G88 inserts will cut aluminum easily, using less power than the other "general purpose" inserts. There is a grade WXN15 which is just as sharp but lasts longer and can be used in other materials when you need the very lowest cutting force in a finish cut. The uncoated and polished grade WK10 is just fine for aluminum and plastics.
The finish you'd get with either style could be very similar, as finish is more dependent upon feed rate than anything else. One thing that could affect finish in alu when using the duller edge of an ODMT insert is that the alu might stick to the cutting edge and coating more easily. That condition of "built up edge" can smear and redeposit on the surface, especially if cutting dry.
