i use a dremel with the reinforced composite cut-off wheels.
it just buzzes right through it.

at least it does on prototyping vector board, and old PC motherboards (hehe).

once i have cut it, then i change to a sanding drum and clean up my edges.
i haven't done this on any long boards. just some small stuff. up to 4"

there are two types of cutoff wheel. don't bother with the thin
non-reinforced type. they aren't good for anything, and have a tendancy to
explode into a lot of shrapnel (the thing is rotating at 30k rpms) if you
accidently flex it. the reinforced type i use to cut all kinds of stuff up to
about 1/8" after that, i go with my angle grinder with a zip blade.

so, that being said, WEAR EYE PROTECTION in addition to the breathing filter.

hope that helps.
