Id This Tool ?

[Treez]

Not sure what these turning tools I found are for , one has a through hole in the brass disc, the other disc has a concave hole but not drilled through all the way.
The tool bit slides out as you turn the knurled knob.
Thanks in advance.

Looks like wire stripper

Might be used on a toolpost to turn down small diameter stock without flexing.

My guess would be a tool with a built in follow rest Looks like you could make bushings for different size rod. It looks like a cleaver Idea.

I think they are turning tools to turn small dia stock. It clamps in a qc toolholder, the brass bushing act as a guide for the matl being turned(probably why the bushing is removable allowing changes in matl dia). The cutter is adjusted via the thumb screws. Kinda like a box turning tool for a turret lathe

Is that a turning or parting tool? I could see using it to part off small diameter wires.

See post 4.
It is used like a follower rest but you bore the hole to suit the stock.
Good for a long thin shaft that you cannot get close to the chuck.
A lot of modellers/clock makers use them. They are quite easy to make and I have been thinking about one for larger diameters +5 mm as they could be more accurate than using a follower rest.
