The grip part is about the size that would allow a man to wrap his hand around them. I am stumped!
From an old plumbing tool box, any idea what these are? | ||

a punch, maybe to swage a fitting or tubeing
I have never seen a swage design like this. All the ones i have used had a couple tapered, and graduated shaft sizes, for a slow expansion of the tube. I Think yours are drive pin punches, for roll pins, shear pins, etc. etc. Just food for thought.
Thanks, guys, definitely a punch of some type.
Aren't they called "bullets"?
Yes, Their a swage or swedge set for likely copper or alumn. tubing. Which ever term you prefer, in my opinion. There would be a tubing holder required also for their use. For whatever it's worth, I was a State licensed Plumbing Contractor for too many years.
Pin and bushing punches don't have beveled ends. They would tend to flare out bushings and roll pins. Swedging or swaging does that mean these are dies? How do you pull them back out? I think they are locating pins. Operator would put part in fixture, use the locating pins, clamp the part then remove pin for machining.
Guess I'll just go with what Rhett Butler said to Scarlett.
