Shop Vac attachment for 4in concrete grinder?

[Herb67SS]

What is the shop vac attachment that goes on a 4in grinder to collect the dust when grinding concrete floor areas? I remember reading about one, thought it was here, and now I can't find it. I have to cut out a cracked tile from my floor and need to gring the thinset down to replace with a new tile. Last time I did this it generated tons of dust.

Thats what happens if you drop a 300lb piece of steel on a porcelin tile floor
Not complaining. I'm super pleased with my tile floor. It was my dumb mistake.

Do you mean a dust shroud? Honestly, it's called a "helper". He/she holds the shop vac hose next to the grinder while you cut the tile out. Not trying to be a smart a**. It's just a lot cheaper than buying the attachment for such a small project.

Shea has a good point. Another thing that might be very helpful, especially if your shop vac has some real suction, is to attach one of those dust shrouds to the end of the hose and have someone hold it. It should help capture the stray dust also. Here's an example of what I mean. You could also make something on the cheap with a piece of scrap plywood.

Thanks guys. I appreciate the responses.
I found one made of metal on Amazon for $28.

I don't have a helper for the guy that's cutting in the tile and I don't trust him to catch all the dust with just a vac hose. Also, I can't afford to have the concrete dust get loose in a shop where I keep a show car, even though the car won't be in the garage while he's doing the work. That stuff has a tendancy to float around for months once it gets loose. And some will anyway.

Sounds like a job that could be done wet? That would eliminate most all the dust at least.

I agree, considering the show car, going wet might be better.

Wet is better in many situations.

GFI??
You will be shocked or worse using a conventional hand grinder wet.
This should only be done with a wet polisher/grinder that has a built in GFI.

I have this:
Makita - 195236-5 - Dust Collecting Wheel Guard, 4-1/2 in
I used mine once to grind down a high spot in my living room before I put down wood flooring.
I'll sell it to you if you want to buy used. $40 shipped.
PM me.

If you are getting rid of thinset, use a vibratory tool?

Cold chisel and hammer works too for such a small area.
