what is this?

[Grass Roots Farmer]

This set of little metal pieces was enclosed in the metal storage capsule as shown. The tips are shaped and the other ends are squared as if they are inserted in a holder. All appear to be similar. I can find no maker marks.

What are these? Ideas welcome.

Thanks.

Looks like the little drills, that came with the early type yankee screwdriver, or push drill.

Upon further inspection, I see evidence of heating. soldering iron tips, perhaps.

I remember them as Yankee drill bits too !

Stuff for fancy leather work?

For digging the wax out of your ears?

Engraving tools?

If the ends are square they are probably for a hand sewer, like you'd use on leather- a handle with a bobbin and a square chuck up front or hold the tool or needle. Usually those bits get lost. You put it in the chuck and twist back and forth to got through the leather. I have 2 of those rigs and one has a couple of those bits in the handle.

All the Yankee bits I have are round shanked with an indent in the side for the lock. I made one that fits mine and put a socket on it to hold modern screw driver bit. The original "Cordless Screwdriver"!

maybe woodburning?

The case is for carrying the lead used in old mechanical pencils. I have several of them in my desk drawer. The other things are soldering tips for soldering on small electrical circuits. Square ends are inserted in to the soldering iron and held in with a set screw.
