The square bit might slide off the end. I’d guess the square bit is an add on that goes into a crank extractor and other cassette remover type bits or sockets that are used in a similar way to the end of a ratcheted wrench. I used to have one like it with several bits that would fit on it.

Looks like the wrench from an old-school cassette removal kit. You’d fit a sprocket on the end of that to hold the cassette in place while you’d use a chain whip to unscrew the cassette.

It’s called a dingle whopper for shlacking saddle dingles.

Since it’s part of a tool kit, it is intended to fit in the square-drive socket receptacle of another tool in the kit (probably the 20-spline BB tool). This allows them to convert the 8mm hex key into a tool that can turn the other tools in the kit, without needing an adjustable wrench or anything else to turn those tools.

I have the same one. Use it to remove cassettes
