Tempered bottom on a 10g? Guess I got lucky. I think the two I have are All Glass brand.

I learned this the hard way when i was younger.
I don't want to hijack this thread, but your thinking is a little flawed. If you have a drill with metal parts, they will be grounded by connection to that third wire in the power cord. If something in the motor should short and somehow apply the "hot lead" to the metal parts of the drill, the ground lead provides a path back to the electric panel. This completes a low resistance circuit and will trip the breaker. Without that low resistance path YOU could become the return path to the earth.
I would not suggest removing that reference to ground on your cord. If you are worried use a battery drill as stated. If a corded drill motor is what you have and you are worried about this, just plug it into a GFCI outlet. Any leakage current will be detected and the GFCI will trip.
