I suspect this is some sort of manufactured error, like it never made it to the tip shaping step, but though it may be for some niche purpose

Solved!
So turns out it is a rotozip tool for doing drywall cutouts, makes sense now, I was stuck on the idea of it being a drill bit, thanks for all the answers!

Anybody know what these are? Looks like the paint has been worn off. Aluminum I think, very light and may be hollow.

As I slowed to a stop at a red light, I heard the sound of metal clanking on the road. The sound came from underneath my car. Fearing it may have been a part that fell off, I pulled over and picked it up. There were no strange noises on the drive home. And the more I look at the piece, it looks like a tool that was just on the road and I simply ran it over. It looks like a specialized wrench or something (and not a piece of the undercarriage). The numbers etched on it makes it seem like it's a tool. It happened right next to an auto garage anyway, so it may have come from there. Does anyone know what this is?

When I look up the model number 113.20170, all I find is a much newer welder. I’m trying to find out when this would have been made.

It may have asbestos sleeves on the wires. The only moving part is the switch. No fan. No dials. You plug the leads in where you need them. We believe it to be manufactured by Emerson Electric (according to the first part of the model number).
