What are they?

[Steven Johnstone-Mosher]

I've just received these "pins" (?) along with some old broaches. They shafts are all 1-3/4" long and .068" diameter. The smaller diameter "pins" at the ends are all just a hair longer than 1/8" and the diameters start at .022" and go up to .033". I was told that they're watch maker's tools, but I've no idea. Can anyone identify them? http://members.aol.com:/steve45jm/private/pins.jpg

Many thanks,
Steve

I'll risk sounding stupid and take a guess. Hole gauges?

Thanks guys. Both suggestions are resonable and logical. Always a pleasure to to be part of this bulletin board.

To me, they look like "sub punches," which are essentially "disposable" tips that fit into a specially designed staking tool punch. Their purpose is for driving out pieces of broken screws, etc.

Since long thin tips like these are easily broken when doing tough work, it's more practical, economical, and convenient having them in small "sub punches" rather than risking the destruction of entire punches that are part of the regular set.
