This made a distinct smell, too, from the ozone it generated.
The great thing about those old metal housing drills is that when there is an electrical short inside, the WHOLE gun becomes charged. So when you get shocked, you are already SQUEEZING the thing that is shocking you. And because an electrical shock causes muscle spasm, your finger clenches the trigger even tighter and you can't let go. You CAN'T let go so the shocking continues. And if you try to rip it out of your hand with your other hand you are double F'd. Gotta unplug it with your other hand instead. But it's difficult to think calmly while you are being ZAPPED.
