I will shortly be changing the position of my electrical sockets in one of
my bedrooms. Currently they are surface mounted sockets, but for neatness
I
would like to take this opportunity to change them to flush fitting
sockets.
When I have previously attempted to fix back boxes into walls on previous
jobs, I have always had problems getting the box square, and sitting flush
in the wall. I have previously only used a drill, hammer and bolster to
create the hole for the box. Recently I have seen these Box Sinker Sets
that
fit to an SDS drill to create a perfect hole and they also are used to
channel the wall out for the cable, has anyone any experience of using
these? If so, are they worth the investment? (not just for one job), or
has
anyone got any other tips for me to make the job easier and neater.

Thanks in advance

I agree with what most others seem to have said - an SDS drill with a chisel
attachment is a good way to do it. I recently did three in the bedroom into
solid brick without any trouble (there was an incident involving drilling a
fixing hole too deep and coming out the other side of an interior wall - but
that's another story!) - there was some making good to be done but by the
third one I got quite good and this was minimal. Again, as others have
said, there will be some making good required where the cable goes so
another bit around the box won't matter!

Another thing to bear in mind is that if you make sure the box is sunk
deeper than the surface then it doesn't really matter if the box is not
entirely flat or level - most boxes alow one or both of the screw holes to
move up and down alowing you to level the socket before tightening up - it
will also pull flush to the wall so even if the box is all to cock it will
probably look okay in the end (unless you really bugger it up!)
