    I would say extension taps also, and a couple of them look to be coated. TIN maybe? They can make good scribes.
    Tap shanks are usually an under size dimension so probably not a transfer punch.

    They do appear to be repurposed taps. I've never seen long taps like that before, but I'm sure they would exist. This probably came from Boeing surplus or something, and somebody spent hours grinding then into punches and scribers.

    Looks like watch makers centers.

    They would have to be small though. JR

    Do they happen to be valve guide bore sizes ? Did they come from an auto machinist or engine rebuilds ?

    Looks like punches made from pulley taps.

    I don't know what they are, but this gave me the idea to make a bunch of random stuff like this to fill a drawer of my toolbox, just to confuse who ever inherits it when I go.

    I would have gone with "broken taps made into punches", but I've never seen a tap with that much shank before it became threaded. Of course, perhaps that's how they broke - easier to wiggle.

    If they were tungsten they could be tig electrodes ( biggest I’ve regularly used 1/4” sylvania green band), centres for a watchmakers or clockmakers “ turns” looks lathe ish but two opposing centre points, posh nails, tyre prongs, some kind of mini sabot round for a smith and Weston, splinter diggers, I give up though my immigration is now zooming along

    Stuff turned into other things through grinding, turning and milling which can be further turned into other stuff via various other processes.

    Taps that broke in the CNC while the operator was sleeping.

    Practice work pieces from a grinder? Wild Guess due to differing mounts and lengths .

    Transfer punches? Can't explain the square ends.
