Hi,

I have some plug sockets in my bedroom which are the external box
type, just screwed to the wall. I am currently decorating the room and
want to get these sunk into the walls so they are a little neater.

I have done this before, with a hammer and chisel, but the results
werent great as the back edge of the hole i created wasnt very flat
and so was hard to drill into and screw the metal insert to.

I know you can buy guides from B&Q etc that you place on the wall and
drill a series of holes which you then knock out, but I wonder if
anyone has any experience of using these and whether they are any
good? Is there another method I could use to get this job done?

They are solid, brick walls, not plasterboard partitions.

Thanks

Tom
