Cutting Really Hard Porcelain Tiles.

[StevieBoy]

I am currently doing a new build where the customer has bought some tiles from Porcelenasa.
They are 440mm x 660mm porcelain and are the hardest most evil tiles I have come across in 20 years of tiling.
I bought a Rubi TX-900n from Dave at Trade tiler as my TS -60 wouldn't entertain them and even it won't cut them properly. I have lubricated the scoring wheel with the oil from a rubi maintenance kit, scored the tile a few times either end more than once, and they just break where they want to.
My next step was to buy one of those montolit blades for my mini grinder, now it does cut them but chips the edges like you would not believe.
My wet bed cutter was the same, chipped the edges etc.

I've tried scoring with the rubi, then using the montolit but that didn't work, tried putting tape on and cut through that but that didn't change anything either.
The cuts at the
top I can get away with, as the chipped edge is disguised with the grout - but it's when you come to doing the L shapes around the top and bottom of the windows that I'm struggling with.
I contacted Dave at trade tiler, explained everything to him and the method I was using with the Tx900n and he reassured me I was doing everything correct.

So has anyone else come across these, and if so how did you cut them with no chipping?
Thanks.

First try some cardboard under the tile, also once scored move the tile an inch or two down the cutter before breaking because if you look the solid centre bit of the bed is away from the edge ive had this problem with my 750 mate thats my 2 pence

Maybe try scoring back too and tapping along the back with pin hammer before trying to break on ur TX

Haven't used a Sigma Andy so I didn't like the post! Haha
However!! I am actually considering a large format one....
So watch this space! Haha 😉

Ive used siramics the once but the breaking system is the same as the tx so cant see much of a difference although i remember watching a vid with prev members having a comp, sure the thread will end up linked but that was purely about who can cut the thinnest slither! And who needs a slither other than 3 fall with those class glass cuts! Lol

Thanks chaps, will give both methods a try and report back next week.

Still not sure how I'm going to cut the L shaped ones though without chipping the edges. 😡

That was done with a Montolit glass blade Ash, on a wet cutter mate.😀
