Jigsaw blade for veneer plaster?

[Toolpig]

Nothing dulls blades quite like veneer plaster, in my experience (think drywall with a couple of coats of rock hard plaster troweled on top).  But I've got a couple of situations where I need to cut some nice, neat holes in veneer plaster and want to suck up the dust by connecting my CT22 to the jigsaw.

Does Festool make a jigsaw blade that won't dull as quickly as others when cutting this stuff?

Festool has a carbide blades, HM 75/4.5 and the HM 105/4.5. You could try them.

What type of holes, round, square, or other?  I would suggest something other than a jig saw since you won't be able to control the depth of cut on the jig saw.  Use a rotor zip with the circle attachment or if your making square or straight cuts, screw in a piece of strapping as a straight edge.  You can hold the CT22 hose right behind the bit.  That will get about 80% to 90% of the dust.  The tool also allows you to set the depth of cut so you cannot cut any electrical wires, pipes, etc.
