Other Using an engrving tool to remove broken bolts?

[OCD Solutions]

Just heard about this little trick tonight. You can use the tip of an engraving tool to buzz out a broken bolt?

I imagine that this works well when you simply overtighten and snap off the head but can it work with bound or galled threads too?

Interesting, might have to try it.

My favorite trick is using a spring loaded center punch. Works for me more often than not.
