Wall chaser advice

[misterfish]

As part of our update and extension work we are having the house rewired. I intend to cut chases in the masonary/plaster to hide the wires and trunking (and to save me paying anybody else). So my question is - has anybody used any of these twin diamond blade wall chase cutters and if so what do you think?

I want someting that I can effectively extract the dust from. I don't fancy doing it all with a hammer and chisel. I am anticipating using my SDS drill with a flat chisel to clear out the channel after the sides are cut with the chaser.

So any advice and suggestions would be most appreciated, and SWMBO is keen to keep the dust down to a minimum.

Thanks

MisterFish, When I cut a hole in an outside wall to put a door in I taped a layer of polythene over the area. Clothed in one of those white paper soco's suits and a suitable dust mask, I crawled under the polythene and cut through the inside wall with a diamond cutter. Waited till the dust had settled and the crawled out. There was no dust in the room and that which was under the polythene was soon vacuumed up.

Misterfish...you don't say what material the wall is made of. If lightweight material then I thoroughly recommend the SDS wall chaser bit from Axminster...

Hi Misterfish

I don't think you're going to get any kind of wall chaser that you can "effectively" extract the dust from - far from it in my experience.

A plastic tent as described by Schultzy is must if the room is anything more than a building site. Depending on the material you're chasing into the dust can be horrendous!

I use a cheapo Chinese made thing that cost about 50 quid. Maybe the Metabos etc have better extraction but even if they do I think you'll struggle to find a vacuum that isn't clogged in minutes.

Best o' luck!

Hear! Hear! I use the Armeg SDS chaser bits and they still makle a lot of dust, although I find them considerably better than using a couple of angle grinder discs. The other plus is that you don't need to knock the waste out.

Thanks everyone for the links and advice.

The house was built in the 1950s and although far from a design masterpiece, it is VERY substantially built out of bricks and mortar.

I like the idea of the poly tent to contain the dust and will be constructing similar edifices as I make my way round the house.

I think I will start off with the Armeg SDS chaser bits and see how I get on - then get a dual disk cutter/chaser if it seems too slow. The thing is I've got a fair number of chases to cut.

You'll be OK unless you have Accrington (engineering) brick!
