Large masonry grinding wheels, what do they get used for?

[Strouty]

I have a bunch of these and am trying to figure out if I should keep some, none, or all. Sait Masonry type 27 and they are 9". I saw them on ebay, and they are not selling for much. I figure I will put them with a bunch of auction items if I do not keep them.

Hmmm, I would guess masonry?

Really?

I am looking for a scenario. I just can't see where they would be used, unless it was for cutting, but they seem way too thick for that.

Brick grinding

OK, so everyone is taking my question way too literal. I know they are for masonry, but what situation would call for a 9" masonry grinding wheel?

For the peanut gallery, I am sure they are used for masonry grinding.

Knocking off old mortar off used bricks, grinding old mortar from between bricks before re-pointing, smoothing slag lines off pieces that chipping it off might cause visible damage. notching or trimming a piece so it fits better....

Grinding the lines left behind from the formwork on a large wall pour.

I don't know why I couldn't think of that, everything else they just seemed to big to use. I am going to try one out, see how well they work on concrete.

Make sense. Thanks for mentioning it.

How about the relief-cut lines in concrete flatwork? I know most use diamond blades anymore but maybe from the past?

I much prefer the power of a large 9" grinder when I have space for it. The material removal rate is just so much better. I would rather use diamond cutting tools on concrete, but if you have them, why not use them? I imagine they would make just as much, if not more of a mess than the diamond wheels. I have a helper hold the shop-vac near the grinding wheel to catch as much of the dust as possible. Definetly wear a respirator, eye and hearing protection.

I am most likely going to keep a couple and send the rest to the auction. Unless someone on here needs some, then I would set up a classified ad.
