Hello,

I am about to refurbish a 1960's flat. Walls therefore are plaster on
masonry (brick) and I intend to install 8 "new" double sockets so will
need to recess that number of steel back boxes. Not something I have
done for some years.....when I did I used an angle grinder and it was
horribly messy/dusty.

I have been advised that a so called "multi tool" is the dogs' danglies
for cutting neat holes these days, and am inclined to obtain one along
with suitable carbide blade/cutter tools. My instinct is mains/corded
and 300 Watts-ish.

Can anybody comment on using multi tools for such applications? I'm
most interested in experiences (negative or positive) and hardware
recommendations.

I've got 3 multi tools. Never even considered using them for this. I've
never seen blades for them that will cut masonry - at least at a sensible
speed.

Given I prefer to keep making good to a minimum, I tend to drill holes all
the way round with the SDS drill - then use its chisel to remove the rest.
