Does anybody have any experience of the various types available? I have maybe 5 double socket outlets to sink in ordinary house brick & don't want to spend ages with the chisel.

Any guidance will be appreciated - thanks.

Get surface mount boxes, then you wont have to spend any time with the chisel

When I was in England, I bought a yellow "box" that had loads of holes in it. You positioned it where you wanted to put the box and drilled each hole to a set depth. Then knocked out the rubble.Loy easier than a hammer and bolster chisel.

Over here I use an SDS drill and have a flap of insulating tape on it for the right depth. Works fine on cob and stone walls.

Hello K 8-) as most of the dedicated tools for this job seem to cost a bit, unless you are sinking a lot of boxes it's difficult to justify the outlay.

I use a 4" angle grinder fitted with disc for cutting stone.  The outside dimensions of the box are marked on the wall and the disc used along the marks to cut down to the required depth.

A bit of work with a bolster or a wide chisel bit on the SDS drill and the job is done – over cuts at each corner of the cut out are simply filled with the most appropriate medium.

Thanks Den, that's a good idea. I was thinking about using the grinder for cutting the edges of the cable channels, so it makes sense to use it on the box holes too. Strikes the right balance of cost -vs- ease and speed.

So, one day, somebody might ask a question here in an area that I know about, so I can help them in the same way I have benefited from Omega and general info. But the older I get, the more I realise I don't know nuffink!

And if you hold the nozzle of a hoover in the right place (or tape it to the grinder)  it really minimises the dust which a grinder makes so freely
