If the attachment is what makes it a screwdriver, then the attachment is also what makes it a drill.

An electric kitchen mixer is not a drill. At least, it wasn’t designed to be one. But I could weld a drill bit on there and turn it into something which can maybe drill - if terribly.

Similarly, the ‘device’ part of what we call an electric drill can’t drill anything, not until you put the drill bit in. It’s not a drill in its base form - just a useless handheld spinny thing waiting for a purpose.

But I could add a whisk and turn it into a kitchen mixer…
