It is indeed a drill. If you look closer, the flat section is recessed below the teeth, and there are 3 patches of teeth that look to be at 120 deg to eachother. It will go all the way around...after the last tooth passes on the top the first one on the other side is just coming into engagement. If you had to cut teeth with a file or whatever back in those days, would you not just cut only what you need and not all 360 deg?

Being smart is not necessarily being lazy.
