Hello, just bought one of these to cut large format porcelain tiles and whilst it snaps 10mm porcelain tiles no problem, I can't cut the 18mm variant despite the spec stating it can cut up to 20mm. Have I missed the small print somewhere that 20mm excludes porcelain? I'm using the scoring wheel it shipped so do I need to change this?

Any advice welcome as I fear I may have to return it and use the nuclear option which is a Stihl disc cutter but I only wanted to use that as a last resort.

Thanks

Hi Caley, most 18-20mm porcelain is 'bomb proof'! There are cutters out there will score and snap it but I've never used one, I'd be interested to see the finish of the cut edge. I tend to use a angle grinder with a turbo diamond blade but if most of your cuts are straight, try to look into it hiring a wet table saw. There is a certain knack to cutting the thicker porcelain as it can 'pop' and randomly crack. Try to cut at each end of the cut line first then 'score' the tile all the way along the cut line with a shallow cut just through the surface, then just cut through gradually. I tend to sit the tiles on a thick piece of celetex foam when cutting. Good luck 👍

what model is it?
from what i know, only the tz model can cut 20mm.
I spoke to a rubi technician, he told me that some types of 20mm tiles are impossible to cut, even with tz

The 20mm porcelain is gaining in popularity but I try to avoid it as tend to feel it in my lower back doing the larger stuff. Plus never keen on outside work when having to factor in the weather (that may change after all this!). But it falls into a grey area with it being a job most landscape gardeners wouldn't want to tackle (as rectified, allowing 2mm grout joints with zero lippage) or tilers having to take on adding a whole new element to guaranteeing work that has to withstand the elements over a number of years. Could become a specialist section of tiling on its own.
