In the past I have used die drills with cutting fluid. An air drill. You will need two or three sizes, starting small to larger. Making two or three cuts. Bad news die drills come from a seller like MSC Industrial and are more expensive than normal drill bits. They are hard but brittle, you cannot bend them at all or they will snap. Using the cutting fluid you can drill a stud by hand in about 30 seconds.
