I bought a cheap set from harbor freight and they have been worth their weight in gold. Especially big fan of using them for accurately lining up a hole to my drill press chuck and for installing or drilling out plugged holes.
Thanks for sharing about these Dan.
I learned about using transfer punches when I was a shock and vibration Missile test engineer. We frequently had to modify vibration test fixtures and these allowed us to mark holes precisely on the test site in precision milled 6061-T6 plate rather than send things back to the machine shop.(we had to use the magnetic drill presses to bore the holes and put the aluminum on top of steel.
I should mention -You can also get individual transfer punches from McMaster-carr. I got a wire gauge “G” size transfer punch to use with my StewMac slotted head tuner installation jig, if I use Gotoh open gear tuning machines the drill I need is a metric drill. and then I align on the center with a metric Brad point but and I use one of the Big Gator Drill guides as appropriate.
