what is the difference?

[CD360]

when you type in SBUM76R in the search bar on the matco tools website, it brings up two choices. SBUM76R and SBUM76RB. i cant see a difference between the two. when you click "set details", there part numbers are the same, but they have either an "a" or a "b" at the end of them. they are priced very close to each other. what is the difference between these two sets?? thanks for the help!

SBUM76RB is the newer version:
"•Features a new S2 tool pin greatly increasing overall strength"

So, i'd order that part number not the other one unless you want the older weaker ones.
