When I worked as a machinist, to avoid confusion, we used the
descriptive term of the machine. For example, an electric hand drill
was a "drill motor". The singular term "drill" was reserved for
various size/type "drill bits", which could be used in any number of
machines with drill bit chucks, including drill motors, drill presses,
milling machines, lathes, etc.

If in the Service, a drill might really get confused
