I think a 22 gauge would go through a PCB just fine. ;-)

Joking aside it's 0.8mm in real units and I'm not sure if that is enough.
It depends on cutting geometry, FR4 is softer than steel (the epoxy at least), but stiffer. 

The plate shear I use is just about OK with 1.5mm boards and rated for 4mm mild steel, although I think that would be mighty optimistic even with a gorilla operating it. 

I think a couple of people have a 3-in-1 machine so hopefully they can advise.

I found this PCB board cutter for a little less,

But weighs 114 #, so freight makes up a bunch of the price difference.
Not sure--is 22 gauge steel thick enough to cut PCB's?   I don't know the 22 gauge.    Plus it bends as well as shears.   And slip rolls, whatever that means.     But I wouldn't buy it without a personal recommendation.
