i have done this with good success.
a centre punch,good and sharp and a teenie drill bit will get it started too.
a pilot hole is always a good way to start.
third is for hard bolts,a carbide burr in (i prefer the ball shape) a slow drill will grind away the broken bolt.very slow and compressed air to blow away the chips.
i was the broken bolt guru in the shop i worked in for a few years,exhaust manifolds were my forte'
Cool tip/trick FD! I always mess up the pilot.
Gonna try that. Thanks!
