  Hi

  I've got a curved design in mind for a client and they like porcelain paving . Did you cut a curve in the end? I've been scouring the internet but the information I've found is making me nervous. Straight cuts seem fine.

  I know this is too late sorry, but maybe it can help someone else. You will find it easier with a diamond polishing disc to finish off. The blade will not bend at all so you have finish the edge by grinding. I personally use a 125mm to mark the line, remove as much with straight cuts as possible and then cut lines at 90 degrees to the 125mm cut line and knock them off with a hammer then use the polishing disc to finish it. Essentially think about how to remove it in lines and the grind it back. You do need to be good on a grinder though.

      Not really. And with the diamond polishing disc it doesn't take much to push it back.I usually cut a little shy of where I want and grind the last mm or two back. Good for grinding back corners too. Great bit of kit, I find myself using it for a lot of odd jobs.

      The edges chip for a few reasons:

      1. Too fast, pushing the grinder.

      2. Too deep through the material, a few mm past the bottom for the final cut or one pass cutting.

      3. Wrong blade, 1mm continuous rim porcelain blade is best.

      4. Cutting too much at once, don't go deep on your scoring cut.

  Thanks Corin.

  I will try the grinding disc. When I first started with porcelain I tried a few different ways and quickly settled on the porcelain disc as the only option.
