Dang, mine are in a cheap plastic tray. Good usage for an extra drill index.
Just a light tappy tap tap too. Then use the regular center punch to pick up the little dimple to make it a bigger dimpleThat makes so much sense. Transfer existing holes to a new piece getting them exactly in place. Thank you so much!
I have used them sort of that way to figure out what size a hole was. By no means precise, but better than guessing or a tape measure.I remember my first set I got in a bundle, I thought they were some kind of standard..lol
given the metal case, I bet they're good quality
Knowing my dad, I'd say you're absolutely right. They're in a rust remover bath right now. Trying to clean up and "restore" as many of the things as I can. It's been kind of cathartic being able to spend a few minutes here and there and remembering seeing this tool box every time I was in the garage 30+ years ago.

My 1980's vintage set came with the metal stand and are in the original box. Working as a toolmaker they are very handy! Nice set!

As others have posted, a light tap that's sufficient to leave a small mark is good enough. A regular center punch applied with a regular whack follows, the transfer punch mark is just to have a place the center punch can locate in. Transfer punch sets are usually a bit brittle and the point if easily broken off if you hit them too hard. I regrind mine back to a point, a lathe can also be used, but I suspect they're only case hardened so the new point will be softer than the original and flatten easily.
For holes larger than the set has just turn up a bushing in a lathe. OD to fit the hole, ID to whatever transfer punch you wish. OD and ID need to be concentric for this to work well. You can also wind paper or electrical tap around a transfer punch if you don't have a lathe but it will be a little (.003) off center. You can even sometimes transfer a tapped hole with this set if you don't have transfer screws. Hope this helps someone.
To the OP- Congratulations on the recent addition.
