Brass exhaust washers

Haven't drilled one out in probably over 40 years. I've read on here about heating (with propane?) and touching bees wax to the broken stud to help it ease out. figure I'll do my best to center punch it and maybe use a reverse pitch drill bit, then an easy out if need be.
Good plan. I always start out with a NEW 1/8 inch bit. Gets you centered well. Ultimately might end up drillling it all of the way to the threads.
