porcelain tile cutting problems

[ducktape]

Hi guys - I need some help...

I've been a tiler for 15 years and I've never run across this problem before, I am installing 300 x 600 porcelain tiles and I simply can not cut them without them shattering, splintering or chipping. I started off using my rubi tx 900 because most cuts are simple straight cuts, but the tile doesn't follow the scribe line (I've even tried scoring the back which worked on one occasion), I 've tried scoring the line several times and have new scoring blade. I've tried scoring then dry cutting with brand new diamond blade but it chips (the tile chips so badly I can't rub out with a diamond pad) and I have tried wet cutting with and without a scoring line made first same problem as dry cutting chips too serve to rub out.

Any ideas or thoughts would be great on this problem

Hello and welcome..

Some more tile info would be great..

 

[ducktape]

The tile make is gres fine porcellanato

I think you will find that is the type of tile , not the name of the tile. I only ask because if you can tell us the name then someone else may have used the exact same tile and can be of more help. As it is that type of tile I use regularly and have no issues cutting at all.

I have had similar problems with porcelain tiles not following the scribe line and chipping when you try to snap them using the head of the machine. I found a way around it by scribing on the cutter then leaving the tile in place on the cutter and breaking it with downward hand pressure or by hitting with a nylon hammer. I know it doesn't sound very professional...but if it works......

....forgot to say...a more expensive but easier method is to buy a Dewalt D24000...like a knife through butter!!!!

sorry the tile name is land fusion bianco, I referred to the type gres fine porcellanato as that may have been more help... I'd have a dewalt D24000 but I had all my tools nicked 3 months ago and it is not easy or financially possible to replace all tools in one go. So I borrowed a mates tables saw and put a new blade in it but still chips. I realise we've all had tiles not break right but this is consistent throughout the batch of tiles I have... I m even considering the is a problem with the tiles as in not fired correctly at manufacture they seem to be to brittle if that makes sense???

This is the first time I have encountered this problem, so I thought I would seek help..
