Another... what is it

[RegeSullivan]

This was in my Granddad's tool collection among a number of Armstrong and Snap-on wrenches. Most of his tools were from 1900 through 1940. This looks newer to me. I assume some kind of drill. I'd love to know what it is or was used for. He was a machinist by trade and made many of his own tools. I can tell this isn't one he made, the top would have been solid steel, polished and preserved in cosmoline, wrapped in heavy brown wax paper.

Need better pictures. A bit extender?
Can you get a better camera and a few more views?

What CN said ^. Or something to twist things, similar to drill operation. You hold your palm on the round pad and slide the collar down on the twisted shaft, which spins the shaft and whatever is put into the slot in the "chuck" at the bottom.

I'm seeing a devise for honing or polishing a bore. I've slotted a rod many times to hold a bit of sandpaper and chuck it in a drill motor to spin it. This is a hand powered version?

I figured it was some kind drill but the "chuck" is a slot. Maybe 25/1000th. It also has a hole that looks like it holds the "bit" or what ever goes in the slot. It might have been a rivet. There are no markings other than knurling on the slide. I tried to take a better picture but just can't get the lighting right.

Most likely the bit is a flat spade type. Or at least the part that you would "chuck" is. If I understand correctly then the screw is there to lock the bit in place.

Nothing was standardized back then. It may have been a drill/bit combo that only worked with each other.
