Mystery tool?

[Jason280]

No clue what these are, came in a MAC box I picked up....

They are a transfer and screw set for center punches.

Are these just inserts for another tool, or can they be used as a center punch as is??

They are not center punches per se. You would use these to transfer the center of a threaded hole to a mating piece.

The storage handle has a bunch of threaded plugs with a pointy tip.
You use the storage handle to screw a correct size plug into a threaded hole with the point sticking out a bit. You then put a mating piece, to which you need to transfer the center of the threded hole, on top of the pointy bit and hit it with a hammer. The pointy bit leave a little indentation on the mating piece. You then drill a hole on that mark and you have a hole in the right spot. Very handy when you have to align multiple holes on one piece.

Ahhhh, that makes more sense....thanks!

It looks like they are a tool themselves. I google them and it says they are used to transfer the location of open and blind threaded holes to mating parts. I myself have never used them. I would guess they are used more for machining.

My turn!

This thing has been floating around in my toolbox for years. Any ideas?

 

[coleman10]

Anyone? Didn't mean to hijack the thread. Just figured it would be better to add on to this one as opposed to creating a new thread.

If I had to guess I would say a pointer or center finder for a trammel of some sort.

I had to look that up. Would never have guessed that. I'll have to put that in my "I have no use for this" container.

Thanks, guys.

Don't be so quick to ignore that piece. If you do any layout work with wood, metal or plastic, that would be handy to have.

Very true, now that I know what it's for.
