I have never had any success with any of the stud extractors that you insert into a drilled hole in the stud. They either snap or expand the stud you are trying to extract and jam it tighter in.
I have had success drilling out studs then using a Rats Tail file to open the hole out until the old stud is down to the thread in the parent metal then either picked out the twists of stud or used a tap to remove the last bits.
Its a good exercise in drilling accuracy and hand filing as well as patience.
I have used a decent cordless drill as they are soft start and easier to control than a mains powered drill.
