Hi jj....stainless steel isnt a hard steel...but its tough...you need to start small and work up to the hole size you require...bigger the bit the slower your drill speed....

Stainless steel "work hardens" when it gets hot. Sharp drill, very,very slow speed & cooling lubricant is the way to go, stopping if there are signs the drill or metal are getting hot. Keep it cool!!
