There is a difference! My Snap-on has a collar that sits in the hole and the actual gear rotates without spinning that collar. The Cummins tool is just a piece of steel that looks the same, but does not have the rotating collar. I've used both... . Mine rotates a bit easier. I can actually turn it over with one hand over the head of the ratchet. The other one had just enough extra drag that I needed 2 hands.
Just my . 02
