Are you dealing with plaster? Or is it drywall?

Either way, a rotozip would work, but it will be hell getting
a good straight line freehand. It will also generate a
tremendous amount of dust. I would probably go with a
circular saw with a masonry blade (for plaster). If it is
drywall, I would go with a sharp utility knife.

But, I would not do it that way. I would either pull of the
base board and run it behind it, or run it down through the
floor and come back up where I wanted it to be (that is
assuming that that is possible).

For plaster, I would use the masonry blade on a circular saw.
Much faster, much easier. Put your shop vac hose in front
of the blade to catch most of the dust, but be prepared to
have to dust everything in the room and in adjoining rooms if
you don't mask them off.

The rotozip would work, but would take a lot longer and you
would go through many bits for that distance. You will use a
couple of masonry blades, too, but they are cheap. Remember
that you will have to keep resetting the saw deeper, as the
blade wears down, to keep your 1/2" depth.
