I find myself in the position of having to fit a few back boxes in to plasterboard. In the past for the odd one I just used a hand plasterboard saw to cut out a hole, but I wondered if anyone here has used something like the square/rectangular cutter adaptors you get for multi-tools to do this sort of thing. If so, how well did it work?

Suggestions for make/model?

The worst thing to discover having already cut into the plaster board is that there is a stud going horizontal/vertical in the way. It can help to use a detector around the area you intend to cut to eliminate this as once cut....
I use a laser to line up the boxes and mark before cutting

Change the blunt blade to a sharp one and cut right through that offending stud…. 🤨

I can’t believe this thread is at 25 messages already…. 😳 plasterboard…. Multi tool…. Go for it!

Borrowed one of these once - 'Drywall cutout tool', found it really easy and 'quick' once got hang of it. More time consuming marking out the boxes.

Multi tool wide blade, decent green laser, and a template tool.

The Appleby ones with yellow lug pieces aren’t too bad. Only ones for me..when needed.

Generally prefer them over other makes, but lugs only allow for fitment in single board. No chance they'll fit double boarded walls without cutting away at rear board, so on those occasions I prefer 'lesser' brands.

Multi tool every time for me, but does not work on a solid flint wall with internal sand and cement render 🥴 then its a carbide tip hole saw followed with a hammer and chisel. 😱

Never heard of anyone trying to cut stone walls with a multi tool. I guess there's a first time for everything.

It works.

Ok… only a certain blade on a certain type of block… but if you’re lucky in that respect…
You can basically scrape the hole flat with a bolster chisel. No hammer involved… and make rawlplug holes with a plumbers old screwdriver.

What sort of stone are you going to spend time scraping with a bolster and why would you want to cut it with a multi tool, rather than stitch drill, chisel and scutch chisel?

It's possible to make fire by rubbing sticks together, but most people prefer to strike a match.
