I have a Sears Craftsman drill which I purchased about 15 years ago (well past the point when three-wire cords were common). This drill has a two-wire cord, and the drill states that it is "double insulated". I have yet to really understand this concept. Can anyone explain what is double insulated...the cord, the internals of the drill itself...?
