Cutting a paving slab
 

Is it possible to trim down a 600x600 concrete paving slab along
2 sides with a 115mm diameter angle grinder?

Just wondering if it's a complete waste of time even trying...

It's the thickness that matters...

But yes. If it's a bit too thick or you get bored, after it scoring
as deeply as you can be bothered, and supporting it under the the cut-
line, a good whack on the offcut ought to crack the rest away neatly
enough - apart from the top edge, the rest is all presumably going to
be hidden anyway.

I did it with a couple of bog standard stone cutting discs (I didn't
fancy buggering up my diamond tile blade). IIRC I got about two thirds
of the way through and snapped the slab over a length of wood. Easy if
the offcuts are a reasonable size.

Actually, the edge is going to be visible - it's being used as a cap
stone. I thought of molding one, but that doesn't look doable in 24
hours (unless I molded it in place, maybe).

Cut both sides then as John Rumm suggested. Running along a strip of
timber helps keeps everything tidy.

With a diamond disk easy. Without, forget it.

You can smooth the edge off with you diamond disk too. Fiddly but do-

Yes. Deepest narrow score you can manage, then go along it with a wide
bolster chisel.

I'd do one, then the other.

Personally i'd borrow or hire a bigger cutter with a diamond disc

For one slab? Blimey, you must be made of money.

Will it look odd with two edges cut, however neatly, and showing
sliced-through aggregate particles, and two edges as-moulded?

If all four edges are visible, I think I'd want to run a Stihl-saw down
all four.

9" angle grinders are really cheap (try the Site one) and diamond
disks (from Aldi of all places) ridiculously so. As a 9" grinder is
handy for stone cutting generally, it's not unreasonable.

IMO the key to this is ear protection, as well as a dust mask. It
takes a while.

yes ... but will take more than one disc unless you have a carbide tipped
blade.
