Don't s'pose these GMC "Multi-Cutters" have popped up under a different brand?
Dear Guys,
Back before GMC went Belly-Up, they did these little 450w Angle-Grinder-like one-handed 85mm saws that they called a "Multi Cutter". Here's a picture of one:
Attachment 179729
At the time I thought they'd be a fairly useless item to own, but I now realise they'd come into their own when wanting to delineate a zone of cement-render that needs to be chiselled out to enable replacement. The key to removing limited patches of render is to "score" the boundary of the patch first with a diamond-blade, in order to stop it from delaminating beyond where you want to stop chiselling it off. Otherwise, you get that "drummy" sound in the old render that surrounds the repaired patch. To facilitate such "scoring" relatively dustlessly (if you're dealing with internal walls, that is...), you'd only need something that could cut down about 9 or 10mm with a diamond-blade (which they came with), but which had a fully enclosed guard and a dust-extraction port.
As you can see from the photo, the said GMC unit had these features in a package that was obviously far more "wieldy" and/or dustless than either an Angle-Grinder with some sort of "chaser"-type guard, or a full-blown Chaser, or even a "Twinner". For what it's worth, a Multi-Master-type device just wouldn't cut the mustard in the proposed situation either, due to the lack of a base. Anyway, the GMC things were obviously straight out of China, and doubtless available to anyone in any colour with any particular brand-sticker they wanted, provided that they were willing to take at least one whole shipping-container's worth...
So... I'm just wondering whether any of you might have seen the things recently under a different fake/cheap brand? (and is so, where...?)
Many Thanks,
Batpig.
(P.S. Google shows them as still being available at DealsDirect, but they aint, cos I rang 'em!)

Dear Lignum,
Close my friend. Very close...
but...
No fully-enclosed guard or dust-port...
Pity, because I'll bet it's higher quality than the GMC unit.
Thanks very much for the reply all the same!
Best Wishes,
Batpig.

Looks interesting as I haven't come across this type of machine before - did a bit of a hunt but all I could come up with is overseas but the machine appears to be the same but also unavailable - don't know why.

Dear Bob,
That's it alright! But she'd probably be 110v I imagine. Pity...
Thanks for digging anyhow...
Best Wishes,

Dear Ian,
Hmmm, interesting suggestion... I already have a 5" Wet-Saw though, that I could run dry on the Vac if I wanted to (Heck, I could probably run it wet on the Vac if I wanted to as well...). Anyway, that size of saw is good on long straightish runs, but not quite as convenient and nimble as the 85mm GMC unit for the short shallow freehand cuts that I had in mind. Cheers for digging all the same...
Best Wishes,
Batpig.

Hi Batpig
I've used the Makita to make cutouts in 18mm fibre cement sheeting
The base is adjustable (using the butterfly nut at the front) to control the depth of cut over the full depth rangeregards from Alberta, Canada

OK I'm up for the challenge,
how about using a Fein
which now comes as a cordless
or the Bosch
or the Fein "construction cutter"

or one of these

Dear Ian,
I certainly did consider a Fein-type unit in the initial stages, and I even went in to the Tool Shop at the BigB and had a long hard look at the Bosch version, which they're currently doing with the grit-type blade amongst the accessories. What concerned me in the end was the absence of a baseplate, which I think could make a difference with the convenience of the cutting. Those Arbortech's you also mentioned are indeed quite a weapon, and they also crossed my mind, but the price put me off a bit for the limited amount of cut-depth that I was trying to achieve...
What really did interest me, however, was one of these Dremel Trio's. They're like a very mini Router, and they can apparently cut just about anything via high-speed rotary-action:
Attachment 180891
I think Bunnings are doing them for $169, but I'd have to then shell out extra for the Vacuum Adaptor, and the proprietary-sized-shank Carbide Bit for cutting tiles, etc.
I'm going to explore the concept, however, by shoving a coarse-fluted Die Grinder-type Carbide Burr in one of my spare Routers, and seeing how that goes:
https://www.woodworkforums.com/f13/ca...render-140403/
If I get a decent-length "tree" or "candle"-shaped one, I should be able to plunge down to the required depth with it, and then start cutting sideways. I use a "cylinder"-shaped one quite often in the Drill to enlarge holes I've made in ceramic tiles for tap-penetrations, etc, and it hasn't gone blunt on me yet, so they must be pretty hard. Hooked up by hose to the Vac, the Router's Dust Port should make the whole process relatively dustless.
With a bit of luck, I might be able to test the concept late next week, so I'll make sure to let you know how it goes .
Thanks Again Ian .
Batpig.

Dear Batpig (one day you'll have to explain the source of your appellation),
have you ever used a Fein?
Because the cutting action is an oscillation rather than a rotation, you can feel when the material being cut changes density or composition -- which might be why something very similar is used to cut through people's skulls. The saw cuts the bone but the surgeon can feel when it's gone through the bone and stop cutting before hitting the brain tissue.regards from Alberta, Canada

Dear Ian,
I've been doing my best to avoid that particular Thread actually!
No, I haven't Ian, but I have definitely been looking for an excuse to buy at least one of the clones. The only thing is - this F/Y is shaping up to be a high-cost/relatively-low-income exercise, and I'm already staring down the barrel at having to buy at least a Makita Screwdriver quite soon, as well as possibly one of those TradeTools Plunge/Track-type Saws not too far down the track. Each week we're having to pick up more bits and pieces. Last week it was one of those $69 Aldi Diamond Core Drill sets, and this week it will be a $44 64mm Remgrit-brand Tungsten Grit Holesaw. It just goes on and on, so the Fein-clone will just have to wait in the queue until its number is called .
Yes, I think I understand what you're trying to say. They definitely sound handy alright. I've had a couple of close calls with having to buy one in the past, but each time I've managed to somehow get by with what I've already got. There's politics in everything you know. Anyway, one day!...
Many Thanks again,
Batpig.

Buy one of these and you can fit the guard to any grinder.
Dustless Technologies#–#CutBuddie™ for Dust Collection when Tuckpointing, Crack Chasing and Decorative Cutting with a Hand Grinder
you have zero chance with multi master or fake as you will burn through the blades, they have a dimond cutter for removal of tile grout but cutting render
i have used one of these with a diamond blade hooked up to vac to cut terazzo in a shopping center with no dust or issue.

Dear Gaza,
Not a bad suggestion; one of them on a 4" Grinder would be fairly wieldy...
But...
Holy Smokes!... Have you seen the price on them over here? (as in AU$249...)
I might just give the "flame"-shaped Carbide-Burr in a Router idea a whirl first, before I surrender to the idea of shelling-out Big Time on Chaser-type Guards. Heck, I'd have to go out and buy a 4th Angle Grinder to begin with, just to do something like that justice (Where does it end?...)
Many Thanks,
Batpig.
