A really nifty trick in removing studs is a set of left handed drill bits, I was fortunate to acquire two sets from a friend in the USA, Cobalt brand. I run them in my 18V battery drill in reverse and just like David says, center punch carefully & then drill with a small pilot drill. The advantage of the left handed drill bits is that due to the heat they generate there comes a point where they usually grab the remaining bit of stud and it just unwinds out the threads & voila the stud remnant is out. Stick the end in the bench vice and gently wind the drill the other way to remove the remnant off the drill bit.
Carefully & with a steady hand and steady eye will do the trick
