center punch ... give it a nice tap, that should keep the bit square on the stud. are you gonna heli coil it after wards or tap it

Grind the exposed screw off flat and center punch it.Then use the smallest drill you have to drill a pilot hole completely through the screw.Keep going up a size until the screw goes away.When you get the screw remains mostly out you can try to run a tap into the hole to clean out the rest of the threads.
GO SLOW!!!
