Can anyone identify the type and purpose of this tooling

[GreensandsParticipant @greensands]

I have had this collection of small circular tooling for some years now but I have no idea as to their original purpose or discipline. Are they part of a watch makers tool kit? They came in a small plastic wallet. Somebody is bound to have the answer

Hi

They look like oxy-acetylene nozzle cleaners/ reamers, I’ve got a BOC set in a little metal case, donkeys years old.

They look similar to my Oxy torch cleaners, also in a steel box.
The other one that springs to mind, is similar, but cleaners for a de-soldering station.
Essentially a soldering iron, with a hollow tip and a vacuum pump.

Hi, definitely look like oxy-acetylene nozzle cleaners to me, the set below has five of the thinner ones missing, but I do have a couple of the BOC sets in the aluminium case, although I don’t have much use for them now.

Regards Nick.

Does your answer imply that there is a different tool for cleaning oxy-propane nozzles or natural gas jets or propane jets?

It is not the case that the first answer to the question is a little too specific?

Hi DC31k, sorry if I’ve implied that the O/P’s photo is dedicated to oxy-acetylene nozzles, but I did say they look like them. Those in my photo are “BIG” company ones, and both these and my BOC ones are dedicated for oxy-acetylene nozzles, as they contained the correct sizes of cleaners for their full range of nozzles for cutting and welding. They may or may not be suitable for oxy-propane, or propane or other gas nozzles, although you shouldn’t need them for oxy-propane cutting nozzles as these are a two part nozzle, which can be separated for cleaning.

Regards Nick.

P.S. I saw the O/P’s photo before I’d read any of the previous relies, and instantly thought they looked like oxy-acetylene ones.

I would say yes, there is a difference.
These look like tools for cleaning the copper nozzles on welding/heating gear, which get gummed up and damaged; or a de-soldering station, as I mentioned earlier.
Natural gas or propane jets, or butane for that matter, are a fixed size for metering and shouldn’t be reamed out with anything at all, similar to jets in a carburettor.
An exception might be a pricker for a liquid fuels stove, such as a Primus, but that is a fixed size wire, suited to the jet.
The specific oxy-propane nozzles I have are a different design to acetylene, and use a metered jet, which changes the flame shape/burn, though I also use small acetylene nozzles too on my oxygen concentrator/propane rig; they work OK with care.

Very similar sets of round files are available for making the grooves in guitar nuts and saddles e.g.
