Dry cutting porcelain tiles

[Fraser Tiling]

depending what surface you are cutting if its smooth i would start with a 6 mm wheel it gives a far sharper
fracture line and deeper a little oil will let it run a lot smoother

Just got my van back from being repaired after a mechanic didnt shut the bonnet properly and it flew open at 70mph.
Found two 8mm Tx wheels, so will try them tomorrow.
Today I've been scoring 5-6 times per cut and appears to be working.
Short term solution but will suffice till I organise new cutting platform.
The tiles aren't flat, slighty textured imitating a polished concrete, an no more visible cuts left to do, so major panic over.
However, before I do my next plus 600mm 10mm porc floor, i will def sort a new cutting platform.
What concerns me more is the amount of travel in the rails mid cut to obtain even pressure.
In my experience with large porc tiles they all require a slighty different amount of pressure to get best results, and these particular tiles are more testing than normal.
Thanks for your help, I work by myself mostly, so dont get much chance to pick others tilers brains on problematic issues,
so your help is appreciated.

Are the tiles by Florim by any chance?

Unsure, didn't supply them, came from somewhere in Watford.
Horrendous looking tiles in my opinion, have a varying dark grey edge on some of the tiles. I refused to lay them until the customer confirmed she was aware of the design.

Hard to tell, although they could be Florim boxes there. 2 to a box.
If they are, then the last lot I fixed were very awkward.
I had to score quite a lot harder than usual - still just once though - and break them quickly and firmly.
Had good results though in the end...

 

[One Day]

Yes - just got a zoom on the boxes - it says Rex - Florim.
Damn nasty expensive porcelain I found.
Show them who's boss - score really hard and break hard and fast.
It worked for me...

I cutting 1200x600 10mm glazed porcs using 8mm wheel - Only scoring once but needs a lot of pressure.

Today I set up a platform on two saw horses, supported 18mm ply with two 100x50 timbers under it for rigidity.
Swapped the 22mm bearing scoring wheel for an 8mm and WD40'd the lot.
Applied alot of pressure, scored once, and again the tile only partly snapped about 100mm from the top.
Gone back to scoring a few times and they break well every time.
Annoying they wont break with just one score, but hey, whatever works.

It serves at least 8 mm, for that type of surface.
but I would opt for the 10.

Thats a 6, 8 and now 10mm wheel thats been suggested!
Just spent 50 notes on two 22mm bearing wheels, looking forward to using them one day....

I mainly use a gold 18mm wheel on my tx1200

I went for the 22mm bearing wheels coz Trade Tiler said they were a "must".
Quite enjoying my new Rubi Giant 20mm notched trowel though.
Will end up with forearms like Popeye, but gives good results..

I am left, 10 mm. much years ago, it was the max
the past several years, from last rubi purchased

if its double loading ie small layer of porcelain on top with 7 to 8mm bottom layer try scribing the top first then turn it over and scribe the bottom break from the bottom try this on a few of your off cuts see if that does the trick .some times you just have to work out what works .when you cut these are there little black spots in the bottom layer when you break the tile .when you set a bench up for cutting dont do it to high you should still have a little clearance between were your legs meet you need down ward force and be able to move with balance and
speed .to high you wont get the right pressure down with movement .it takes a little playing with but you will
know when you get it right it will just flow

Some porca will not cut with just one score , some porca will not cut with any amount of scores, its not you or the machine its the tile

Thanks for the tips Ray, unsure of what the double loading bit means, and will look for black bits tomorrow.
To be fair the platform is a little high, set on two Stanley fold up workhorses, plus 50mm timbers and then 18mm ply.
Have a busy day tomorrow after being informed today that the kitchen is being delivered on thursday and need to complete 20 metres of a Himalayian floor before it gets here.
Will take a few pics tomorrow of cuts to see if you can identify the problem.
Was thinking perhaps the depth of the shaft on the scoring wheel may have something to do with it.
Seems there are so many variables, for now multiple scores work, so will continue doing that.
