Hello,
I am about to refurbish a 1960's flat.Â* 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.Â* Not something I have
done for some years.....when I did I used an angle grinder and it was
horribly messy/dusty.
Forget distributing 240V.
Thread the house with USB power connections.
/me runs, that way... ;-p
FWIW I'm aware of the use of these things in conjunction with an SDS

I have never found one to be of any use.
Stitch drilling and or SDS chisels are the only methods I have found
successful on hard brick. And even then you sometimes just have to bond
in the back box (old bonding and a bit of cement) as the brick collapses.
