Help ID this tool?

From an estate lot, heck if I can figure it out, assume someone here will know immediately. Marked Japan, the rings on the left are sized and fit into the rings on the right, the leadscrew fits all the rings on the left.

Anyone?

Thanks!

I keep a tapered reamer with my chassis punches but I've never seen one included with a kit before.

Greenlee makes a bunch of them and they can get quite pricey.

no sh...t, I picked up an 8 pc set for $4 at a yard sale a few weeks ago. all Greenlee, 1/2" through 1 1/4". I looked them up and it was like $350 for the set!! I was SHOCKED!

crazy expensive...I'll probably never even use them.

The ones I buy for SS are around $250 just for the 1 1/4".

Price the *KEYED* Greenlee knockout sets!

You can easily spend $500 on just ONE size.
e.g. https://www.greenlee.com/us/en/pushbutton-set-30-5-mm?w=2&c=161&b=86&r=30&p=1&l=4&v=c
and they make a ton of specialty chassis punches such as for D-sub connectors.

Yeah... Greenlees hydraulic punch set is ridiculous mine for lock work are just the "cheap" turn with a wrench kind... I just googled these silly things... they are now going for 150.00 each... the typical cam lock that goes in the hole is only 5-10 bucks...
