Wet cutting stone with small grinder

[Ali]

Evening folks.

Did a bit of cutting today, just some small concrete kerb stones.

Don’t have a big petrol grinder with water suppression etc., so fully masked up, dust everywhere, what a pain. I could hire something but for one cut...

But, got me thinking I would invest in some means of suppressing dust on a smaller grinder as I do like working with slate - worktops, garden stuff, furniture etc. nearly always with a 115mm grinder, often a lot of polishing and shaping.

Is there such a tool I can use without getting electrocuted? What about air-tools? It needs to be something pretty lightweight I can use one-handed. I could rig up some form of LEV, but it’s not something I’m doing on a bench where I could set up a hood.

Ideas?

for small jobs id go dust extractor and mask up

Wet cutters are bloody messy

...Wet cutters are bloody messy

Ah, ok - I didn’t know that, I’ve never actually used one other than seeing them in safety videos and buildings sites. I can’t remember now whether they insist on a respirator as belt and braces anyway, but I know I would with a vacuum...

Not much use to you but I'd use my wet cut radial for most wet cutting or grab my Stihl saw

How about something like this.

Aye but a few cuts with the hose on a Stihl isn't gonna make much mess.

Electric 12" often have provisions for wet cutting.

Don't regret picking up an older version of this.
Mess is contained and end of the job a quick hose off is all that's needed once the plugs been pulled.

Big investment for a few cuts.

I wasn't suggesting he did. Linked a cheap wet cut saw above.
Wet cutting doesn't always have to be messy.
Cutting a doorway out inside a house wet is aweful mind.

Prefer a chainsaw. Gorrila tub below and most of the water is contained compared to a disk cutter.

Odd feeling cutting masonary with a chainsaw

Not to mention dangerous?

Diamond tipped chains. Made for the task. Have a look on YouTube.

Always wanted to use one. I know the powerhead is actuall an efco that got rebranded by loads of people

Another school day here - I'll need to find a clear space to carve my initials in....

Yeah, me too...dug a 16m trench for the drain, 18” wide 3ft depth then saw someone on Instagram doing it with a chainsaw...

Thanks for the replies...more research is in order. Really like those extraction attachments, but I don’t mind a bit of sludge / mess either...at least it isn’t bad for your lungs

Diamond tipped chains are very hard work and damned expensive. The saw blade itself is almost a consumable too.

Oh, and not a little bit dangerous too. I know a lad who had one snag and hit him in the face. Made a pretty scar.

Just get something like this

I just use a diamond blade in an old circular saw and add just add a bit of water manually to keep the dust down.

Diamond blade and water is the way to go, we have a wheeled floor saw with a big blade for installing ground loops and there is a big difference in blade life when used wet. Concrete dust is not good stuff to breathe, a good friend of mine passed away recently,an autopsy revealed he still had cement residue in his lungs. He had been retired from an office job in a concrete works for about twenty years, he never even worked with the stuff

Aye. Wouldn't buy one but certain jobs they can be a blessing.

Chain stretch on these things is worrying and I agree re the bar. Covered in essentially grinding paste.

First time I used one was trimming brickwork to one side of lift openings on every floor. (Someone screwed up)
Would have been tricky with a disk cutter.

Started in a mini at 8yo. Progresses to telehandlers and dumper trucks then small trucks before doing my driving lessons in a clio. Felt tiny.

I've had to...and still have some to do...cut a few inches from concrete gravel boards, reduce the height and the length, about 30 of them...yay.

I clamped a peice of angle to act as a straight edge and stuck the hose in one end. Just enough to wash the cut line out and suppress the dust.

Rubber gloves and a 9 inch grinder and make shift diverter to stop it sucking in any water.

Only got a little tingle..... I jest...but in all seriousness, don't do that.
