Ammonia solution also works well.

Do Not Use a Step Bit!!!!!!! It is a waste of money as it will burn very easily going through stainless. Spend the couple extra bucks the first time on a stainless rated hole saw. You can usually get 4 to 5 holes out of each saw bit, which is better than a half a hole with a step bit. A 7/8" hole is necessary for a 1/2" NPT Nipple to fit through properly. Weldless fittings from MoreBeer work if you can get the thru wall fitting to seal properly. I usually grab a 7/8" neoprene washer to do the job right. It is worth it however to get the welded kits from them and pay your local welder a case of beer and have him weld it in. Thanks Steve.I have had great success with a step bit. For me it worked like a charm and was easy to use on stainless. Much easier than a hole saw IMO.
I have them for 40.00 a piece right now, but with the supply of used Cornies dwindling as more and more home brewers moving to kegging, prices are gonna go up again shortly. I might have to start converting pin locks over just to keep them affordable.What's wrong with pin locks? I've got several of each kind of keg, but find the pin lock ones much easier to use.
