Yep, exactly right. I have a set of core pins I use for breaking them out (punch press pins). They do make diamond bits you can use in a die grinder that will work. The biggest issue there is not messing up the threads that are in there already too badly. I would try breaking it out first. Big whacks since the tap is strong but brittle.
