OK, I understand that on a lamp it's a good idea, or the socket shell
and bulb threads will be live if the hot side of the power line is
connected to that part of the socket.

Maybe they want the hot and neutral to be determinate just to protect
against lawsuits?

Or, maybe it's a UL standard even for plastic-housed appliances?

Or maybe the exposed metal chuck and drill bit are somehow connected
to the motor within? Ya think?

Sheesh

Here's a patent describing an insulated coupling that electrically
isolates the chuck from the motor in a double insulated (class 2)
power tool.

How well does it work submerged?

You bet your life!

Submerged, it isn't going to make one bit of difference which way the plug is
inserted in the outlet.

Wet, okay Mr. Picky?
