What are these Things?

[Bigcypresshunter]

I found these three metal things in a cigar box that appeared to have dental tools in it. The unidentified pieces are all threaded and tapered down almost to a point. The smaller two have the same type of bottom shaft that would fit in a drill (like a drill bit). The larger one is 4" long and has a different bottom and what appears to be the initials "RH". What are these things? I figured someone would know.

those are buffing wheel arbors. they go on the shaft of a motor and the buffing wheels screw on to the arbors

Would a dentist use these?

They look like universal re-threaders to me. To get that dang bolt hole aligned again. Of course if they were found with dental tools, they might be a vet's tools for giving root canals to animals. 8)

I agree. For felt or muslin buffing wheels. Too large for dentistry, but maybe polishing false teeth, etc. on the bench.

And other folks beside dentists use dentist's tools. Handy for model makers and builders, fly-tyers, etc.

Note: The extension versions like above are marked RH & LH for the threads.

Bingo, we use them with a felt wheel and different grits of rouge to polish gold and silver jewelry.

Many dentists cast their own gold crowns. They would have to buff them out before they could put them in. Make them nice and shiny.

GALT 1073 nailed it, good call GALT 1073.

I was at a friend’s house yesterday who happens to be a silversmith. He's using some of my gold scrap to cast a ring for me. It's an alien ring and it just so happens that the buffer he had on his work bench had an arbor like that on it. I asked him about it and he said it also hold a grinding wheeling.

The arbor on his buffer/grinder looked exactly like the arbor in the middle of your photo.

Thanks for the ID everyone. Even the "RH" was IDed. Maybe I will keep these things.

Mine doesnt have set screws. I dont know how to attach it to the grinder, buffer, motor or drill.

I didn’t see set screw holes on his arbor either. The shaft on the motor is tapered and the arbor is wedged onto it. That’s the same quick change set-up that lots of drill presses use to attaché drill chucks.
