If you have coolant thru on your spindle check out Guhring's Firex series...used 'em on H13 tool steel, 1346 3/16" diameter holes thru a 3" thk block....(went from both sides but still...wow)

As for milling,yes, you want a variable helix cutter, I love the Hanita Varimill for SS, they are very tough and last a long time.
