Drill cases are made of plastic to keep the operator from being electrocuted. This is called "double insulation" - the wiring inside the drill is insulated, and the case of the drill is a second insulator.
Some of the gears in a drill are made of nylon because nylon is strong enough for the application and it's less expensive to form into a gear shape.
