Everyone I know uses an angle grinder. I'd probably get a cheap one to do this though, plaster dust will kill a nice one like a Dewalt/Bosch/Makita quite quickly.

Gaffer tape your vacuum cleaner close in to the side to suck in most of the dust. This is what we do at work on the routers etc.
 
You can actually get a dedicated wall chaser for under about £50 now, iirc it's basically a pair of angle grinder type disks in parallel, in what appears to be a modified circular saw body.

That might be the fastest/easiest way.

We used an SDS drill when we had to do some a few years back, and it was extremely messy, fairly slow, and very noisy.
 
Cheers guys. it is a brick wall plastered over. They are pretty hard bricks.

Interesting - dedicated wall chaser, I will have a look but so far I've only seen ones over £100!

Cheers,

I just use a bolster and hammer the 2 outer sides of the channel, then bash lengthways with a brick chisel

edit, although grinders and wall chasers might be easiest, the dust is mental
 
I've been reading around just now and quite a few electicians and plumbers saying they use these.

Not as quick or neat as an angle grinder, but not much mess.

Might try one and see!
 
My 2 best mates run an electrical contracting company and use angle grinders and chisel attachments themselves and encourage staff to do so. I would imagine if those are any good that they would be more common.
 
Interested in this, as plan to do the same. Only our house is a 1850's stone house. Would one of the mentioned above be man enough to do the same through stone? I say stone, as some walls are mainly stone, kinda weird how they built houses back then!!

Angle grinder should be fine for that with the correct disc. I used hand tools when I did all the water pipes and network cables in my house, took some time but wasn't a bad job. Dust didn't bother me as the whole house was stripped anyway.

Last time I ran water pipes outside from a borehole to a greenhouse I angleground a channel in the concrete and used a kango to trench, worked well.

Yes, by quite a wide margin but it'll be a lot slower too. Total time taken compared to the grinder with the cleaning up afterwards will probably be roughly the same though :D
 
I'd not even Bother trying with hand tools unless you only need to do a meter or so.

saying that I had too last week when our Kago broke. still cut it with a grinder 1st then cold chisle and hammer on a stone wall. was just glad it wasn't a reinforced concrete wall like most are over here.
 
Have you looked at the local building Hire Shops? See how much a dedicated chasing machine will be. There might also be one with a dust removal sytem (attach to a vac) or at least a bag to catch some of the dust.
 
Drill 2 sets of holes in the wall (either side of the channel) and play a messy game of join the dots.
