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.

Cheers.

Brick and plaster? No chance! These things are fine for cutting holes in
plasterboard when you have stud partitions - but no good for solid walls.

You need a decent SDS drill, followed by an SDS chisel. Even a box
sinker would struggle on brick, but is ok on block walls.
