What years are we talking of for the two cassettes that you mention? I know an ex pro-team mechanic who might have the answer.
NB, I think that some of the terminology that you use is a little confusing
Both my 1999 STX-RC hubs and my 2010 Ultegra 6700 hubs use:-
1. A splined, circular (Park) tool to remove the cassette from the freehub body (freewheel).
2. An hex allen key ( think it's 10mm ) to remove the freehub body (freewheel) from the actual hub - to do that you need to remove the non-drive side cone from the axle, withdraw the axle (from the drive side) and recover the loose ball-bearings first.
The bearing surface ( for the drive side hub bearings ) is incorporated into the permanently rotating inner element of the freehub body.
Had to do the latter on the STX hubs, 12 months ago when the bearings between the two elements of the freehub body went shot, transferring an unacceptable amount of "float" into the cassette.
