My dad had 1 of the 1/2" drills when I was working for him 20-25 years ago. One of my tasks with this drill was to climb up on a stack of plywood and drill 4 holes through it using a 2 or 2 1/2" (can't remember for sure) paddle bit.
It caught and threw me right off of the stack.
Don't remember what the plug looked like then as we were but humble carpenters at the time.
I seem to remember it being dropped and the case being broken.
