Glazed porcelain cutting issues

[One Day]

everything Marc has already said - 100% spot on.

out of interest - what manufacturer/brand are the tiles?

Instead of going full depth on the cut make a first pass at half depth along the full length of the cut using a sponge to cool the disc and cut . Do drill corner first though . Then cut full depth say first 2 inches each end of the cut then full depth next to corner drill hole say 2inches then cut the rest out .

Tried doing just a shallow pass with angle grinder but still same, photo above is only 2-3mm into depth if tile and then the split.

Do a video @Sean Kerry ... lets see how and what you are doing.

Try putting some carpet on your work bench to help dissipate the high frequency resoresonance from the cutting of the tile

As Marc @3_fall has already advised, do the two split pieces warp in any way once they’ve split?

 

[Time's Ran Out]

As I’ve got older I’ve certainly mellowed.
I was about to reply almost word for word with @3_fall but now it’s just - 134m and the tiles don’t cut!
And all this advice is free.

I would like to know how this went .

Had the Rep out yeaterday from thd distributer and he was happy with everything that om doing and the equipment being used and he also filmed me cutting 3 tiles and they all split at various points. He thinks tbey may have been over fired and are getting intouch with the factory in india. I'm plodding on with as i need to finish the room ive started. Thanks so much for everyones help and advice.

It costs more to send the rep out than it does to replace the whole order, yet they make us jump thro hoops to prove we’re not idiots and can cut a tile with a wet machine.
They buy this stuff in at less than a fiver a M2, generally £2-3
It’s a joke
What happens if your replacements are all a different shade?
How’s that going to effect the job as a whole?
Will it matter?
It’s far too common now.

My advice - don't let them keep you waiting.
Invoke consumer law - write/email them letting them know that the tiles aren't fit for purpose and are faulty.
If you wait, I reckon they will not do anything.
Nobody will admit they are over-fired, but the cut problem proves it.
