I do a lot of 303 and 304 stainless (about 2" x 2") parts that I need to polish to a mirror finish afterward. I need to know the type of face mill you would use for a very smooth finish.. Right now I have to spend hours sanding before I can polish, (to get all machining marks off of the parts.) Right now I use a positive rake 4 edge insert.

I thank you in advance for your suggestions on face mills and inserts.
 
I would consider what you have a roughing tool. keep using it, just add a flycutter and leave .005 to .010 for a finish pass. Just make sure that the swing on the fly cutter is larger than your part, shouldn't be difficult with how small your parts are.
 
look at a sandvik 345 face mill. 8 cutting edges per insert, it's good heavy insert with replaceable seats, and they make a wiper insert that replaces one of the 8 edge inserts for better finishes, letting you use a semi-roughing speed and depth of cut and still get a good finish
