Yes and no.
Works ok on steel but the blade doesn’t actually cut, it deforms it, so with thicker alu you end up with a lip you have to then file off.
Nowadays I use the pipe cutter to mark it, then follow round with a hacksaw blade on the surface – i.e. deepening the mark into a groove all the way round, not simply sawing through it from one side. You can either start sawing when the groove is deep enough, or just keep going until the bit falls off, which is what I did with my carbon fork.
Despite Trail Rat’s mega skillz willy waving, I wouldn’t risk sawing straight through. Very easy to bugger up an expensive component for the sake of 5 mins effort.
