What is this?

Puller most likely, but (I think) it could also be a chain breaker. Although that would be one big chain....

It removes the orifice from inside of a Falange valve.

All excellent possibilities for use

It is a puller of some sort, likely a condition where it can't get inside the part.

Or behind it.

So they clamp it by the OD.

I have that Harbor Freight set. It actually works well.

I think you've put your phalange on it!

It might be my company's new dental plan?

It looks EXACTLY like the tool I could use to pull the empellor off it's shaft on the Kubota snow blower, "nearly" all in pieces in my shop.

What size is the hole in the split clamp part?

1 1/8"

First thought that came to my mind was a press/puller for "U"joints (aka crossjoints).
