Default routing stone

Can it be done?
I have just had a new granite work surface fitted. the men cut out an oval for the sink to fit in. They just used a diamond disc in an angle grinder so the edges are terrible.
With some cleaning up this offcut would make a nice occasional table.

Anyone?

I don't know about routing granite, but it's easily cut with your average wet saw.

Now if you could find a bit for your router that was covered in diamonds, that should work. But maybe carbide bit would work as well. Do they make diamond bits for routers?

Not sure if it would need water or not, but you could easily take care of that.

Are you trying to cut it neatly? Or do some sort of design?

OK, fess up...which one of you clowns stole my sig? It was right here a second ago.

Bob; you're living in the land of ancient sculpture...are you saying there's no marble /stone workshops around?! *shock*
An angle grinder would be my first (and only) choice.
Grinding disc for polishing granite, marble, terrazzo and engineering stones

Dan, I'm living in a land that makes concrete copies of ancient sculptures.

Apart from that, I'm a cheapskate. Having paid over 700 US$ for the worktop, I dont particularly want to pay twice for the same piece.

I had a much smaller granite top that I tried to remove when I enlarged the outside kitchen area, but it broke. Because i was buying the new piece, the company cut the old piece square and rounded over the edges for free. So I have one 30" (75cm) square coffee table, I thought a smaller oval, about 30" x 15" would be nice.

What I really would like is a round over edge, I dont see any way I can make that evenly around a permanently curving edge with a disc cutter.
No fancy designs, just a rolled edge oval

Monuments are cut with specialty bits, not sure what kind, but they create a ton of dust, and water is used for lubrication, as well as dust control. Haven't cut or carved granite, but have used a diamond drag bit with my CNC router on granite for some pretty impressive floral designs. A diamond drag bit just scratches the surface, with the router turned off, basically just a bit holder. Not going to help with rounding over, but food for thought for the top.

Bob, do you have a picture of the piece?

havent bothered with a picture. its a cut out for a sink, dark grey granite, 30" long, about 20" across oval shaped, and an inch thick.

looks like i need to ask the company nicely because its not worth spending large sums of money on specialist bits.

It cannot be done with a router, end of story. N

The edge can be rounded over with a series of small grinding/sanding wheels in your angle grinder. But they are not cheap.

Somewhere on YT there are videos of this method, and the edge ends up being polished the same as the surface.

I needed to smooth over some edges on some pink marble tile a few years ago, but it ended up being cost prohibitive.

Probably the best idea.
