I had a broken bolt in an Aluminum head. It was siezed in the head.
nothing would get it out.
I set it up in a drill press, Center punched the bolt, and drilled the whole
bolt out to the threads, then retapped the bolt hole and the final pieces
fell out.
The hardest part was making sure it was centered for the punch, and drilling
straight down the hole. Lucky !
