Hi

I've asked this elsewhere (in the review thread) but nobody seems to have been able to provide an answer, unfortunately.

I've just bought this cutter. It comes with a 10mm scoring wheel. The cutter is designed for breaking porcelain, as its main selling point, however there is no guidance as to whether the 10mm wheel is suitable for porcelain or not. I'm mainly cutting 600x300 porc's about 10-11mm thick. Will this scoring wheel do the job?

I ask, because they also do an 18mm and 22mm wheel and under the sales line on various websites, it states that the 10mm is suitable for clay tiles, the 18mm is for harder tiles and the 22mm is for very hard tiles. Porcelain being considered hard - I would have therefore presumed that I need the 22mm scoring wheel - but if so - why sell a porcelain cutting machine - with a scoring wheel not suitable for porcelain?

Any advice please?

Paul

Because they are selling a "tile cutter" and not a "porcelain tile cutter". Even though they say it will cut porcelain tiles you need to make sure that you use the correct wheel. I personally don't use Rubi cutters so I don't know that much about them but if I was you I would ring Rubi UK and ask their advise, or simply buy the other 2 wheels anyway.

I use Montolit cutters and they only have 1 size wheel so no issues about what to use for this and that - oh, an it doesn't crush the porcelain if you set it up properly either.

Failing that give Dave a ring from Trade Tiler

The 10mm wheel will be fine.....i thought i said that in the other thread.......

The bigger wheels are better for quarries etc that need that extra pressure to get a good score line...

Thank you Dave. In the other thread you said "you get a 10mm wheel and yes others are available for harder tiles etc " which didn't quite help. Sorry.

But thankyou this time - nice to know I can use the 10mm one. I wish Rubi would make their descriptions better and their manual. Would make life a LOT easier.

I use the gold 10mm wheel for smaller porcelain. I use gold 18mm for thicker or larger format.
The 10mm wheel will be fine though to start you off.

Right. I just cut my first bit of porcelain. 600x300 11mm thick, glossy surface tile.

Result - it cut in half. However, the cut is not that clean. There are small chipped areas all along the cut edge - plus the actual edge of the tile has some small/minor bumps along it.

Is this normal?

Is the slight chipping due to me not pressing hard enough on the scoring wheel perhaps? Not having any previous experience with a dry cutter - its difficult to judge. It certainly scored - quite a deep score I thought in fact. I was suprised that it scored that easily. Any suggestions? Too hard/not hard enough?

Practice more. Even after 31 years of tiling i come across a tile which is troublesome to cut. I usually get around it by experimenting with pressure on the score or the snapping technique. Failing that then its the wet saw.

The small chips on the glossy surfac tile will be you scoring to hard.....as for the bumps in the cut tile edge, well this sometimes happens..( depends upon the tile )...use your wetsaw to neaten them up.....

Pressing too hard you say - hmm, I wondered if that might be the case. Interesting, you'd think the opposite. So I need to score a little lighter - I'll give that a try, thank you again Dave (as always very helpful advice).

I need to get myself some broken tiles from the local tile shop and do some practising. The first tile I cut (first ever dry cut) was one of my clients. I figured I'd cut it in half, at least if it went wrong, I'd still probably be able to save the two ends

Can't afford to lose too many of them though, as I need to start laying the buggers next week, after finishing all my wedi board prep.
