I understand FC are meant for surfacing but how much of a cut they take??

For a fantastic finish on Aluminium, Brass & Acetal I use a button insert face mill with ground high shear inserts. Very low power required & super smooth cutting. I used them for tandem milling where one piece was cut with the outside of the insert & the adjacent piece cut with the inside of the insert. This method has no backcutting marks and produced a sub micron finish on Brass.been experimenting with that brazed stuff on a FC and got a decent smooth finish on some 6061 but do have some inserts laying around, will check that out....also experimenting with a 50mm shell mill on some 12L14/1018 which looks acceptable....lots to learn!!
what kind of inserts you have in the shell mill and what are you cutting with them???
has anyone mentioned this one?I had to do a lot of searching for a non-Chinese, indexable fly cutter. This is what I ended up getting:
I chose TPG 321 inserts.
I bought these at the same time as I ordered the cutter head off Aliexpress. I'm quite sure they are neither genuine Lamina nor Swiss made, but they work well. The picture above was taken after milling a bunch of P20 that I am certain approached Rc 40 if not over. Much harder than 4140QT.what kind of inserts you have in the shell mill and what are you cutting with them???
