If you are drilling the stud out and tapping it, you will want to use a 1/4 bit or .272" bit. 1/4" is the most common. If you use a carbide tipped bit you will want to work slowely. If you don't you will burn the carbide off the tip. Start with a smaller bit to get started. Then gradually go up in size.
I have never used masonry bits when drilling out a stud and easy out before...

Alright, you tell him how to use a masonry bit, but then proceed to say that you have never used one in this situation before? I thought we went over this!! If you don't know what you are talking about, STFU!!
Allan, ban this n00b for a week, I will paypal you the money!
No, not all masonry bits are carbide. You want firm steady pressure on the masonry bit and use a LOT of coolant/oil on it.
Did you try the left hand drill bits? It is probably in there too hard now from trying to drill it out, though.
