Introduction: Cutting a Curve in a Ceramic Tile With an Angle Grinder

Hi here is something I posted on You Tube some time ago and would like to share it with you ... now i have discovered this web site.

While tiling a 50msq (538sq ft) floor area, i had to cut the 450mm x 450mm (17.7" x 17.7") ceramic tiles around the spiral stair case & hand rail, which involved a lot of large curved cuts. So I put this video together to show how to cut a porcelain ceramic floor tile with a 100mm (4") diamond blade fitted to an angle grinder.

Unfortunately i did not take many close up photos at the time, but i have attached what i did have and extracted some snap shots from the video to create this slide show

I think it's self explanatory but please feel free to ask any questions ... Thanks Tony i

Hi good question. The Mikita diamond blade saw will make a good cut. Without knowing your pavers i would use a segmented diamond blade ... but ... will you be able to hold a grinder & working cutting blade steady and straight in a perfect line over several meters??? i would not trust myself to do this in a good nice straight line finish. if i were doing something like that i'd engineer & make up a 1m to 2m wooden jig / straight line guide you could place over the paver join line and use a protruding nail at each end of the jig to push into the join line to get it fixed in the correct position then run the cutting blade straight up the guide.
i have also fitted a diamond blade to an old wood saw and cut concrete pavers in long straight lines and as it is a bigger blade will assist in keeping straight but if you push it off line it will go off line therefore i would also use a jig for this.
Good luck let me know what you finally decide on & how you get on, sounds like an instructable in the making.

Thanks!  I'll be doing something like this soon (tiling around a toilet) and was wondering how to do the curved cuts.

Yes! Good luck ... the only thing i would say is the toilet may have some very tight turn / curves which even a 100mm blade may not be able to do.

So i would make a series of 15mm apart straight cuts up to about 5mm before the curve cut line,
then break off all the strips carefully,
then gently grind away the rough 5mm distance to the curve cut line to a neat finish

Good idea!  I'll be sure to try that if, as you warned, the curves are too tight.

Nice! I love your style of control: with the whole body especially the legs, makes perfect sense.  I wonder if you might consider clamping or weighing the tile down some how?

yes, good idea of, course you could do that, just be careful not to over tighten the clamp you may end up cracking the tile. These 450 x 450 Porcelain Floor Tiles were pretty tough & heavy, but if i were to cut a smaller tile i would defiantly secure it down.
