sorry the reply on this is a bit late but if you grind the outside dimensions of the box with a decent diamond blade it will get you within down to about 22mm. Use a decent chisel bit on a variable speed sds and you can get flat backed chases on all but the crumbliest brick (with a bit of practise!!). happy sculpting

It's an art that requires practice, and you do have to plaster afterwards, but because of the extractor it's minimal dust.

By 'stitch drilling' and using a sharp half inch cold chisel, some masking tape and a sheet of newspaper I can convert a single socket box to a double without even leaving the wallpaper disturbed around the new 2gang plate. Just got to be careful is all. Agree there's an art to it though, funny how you get to know just where to give a particular brick a strategic clout to achieve maximal material removal for the least amount of heft and damage.

If on site where the wall has to be plastered and finished, like Tony I found it easy to blast away with a 12mm SDS bit then let the mate square it off. Gives them the practice for domestics.

Yep, that's the one, square up a 2g box, draw round and then carefully cut through the paper scoring the skim underneath. I angle the blade away slightly to produce a very slight bevel and this ensures the skim breaks up inwards towards the hole side not the wall finish side.

it's an artform!

Waste of time and money. I tried one for the first (and last) time on a block wall and it was next to hopeless. Okay for a DIYer doing 1 socket into therma block. I'm afraid it's the old method that works for this. Go and get the Hilti out.

Any of you guys had much luck with a Scutch chisel for the SDS hammer drills? I've held one in my hand at the supply house, but never bought one. I might, if one of you all has used one before with good results. It might be overkill. I don't know.
