Dry cutting porcelain tiles

[Fraser Tiling]

I'm fixing about 90 metres of 10mm 800x800 porcelain tiles at the moment, using a Rubi Tx 1200 cutter.
As per usual with large format porcelain, getting clean consistent cuts is very hit and miss.
Decided to change my normal 22mm wheel for a bearinged version to see if that made any difference.
As expected, little changed.
Generally, as a rule I have ever only scored once, some tiles responding better to a light score, others with a heavier score.
Having no decent results with either, i tried scoring 4-5 times with heavy pressure and seem to get much better results.
Just wondering if anyone else is doing the same?

You say that, but seen other posts saying the Sigma is just as inconsistent.

It depends also on the tile. All i can guarantee is that there are far fewer tiles sigma can't cut cleanly than the large rubis.
Only porcelain I've ever been unable to cut cleanly was a glass topped, pillow edged fanal.

I know what you mean impish I had a similar glass topped tile on the sigma would not break on the handle only way I could snap it was fisting it on the cutter bed.

Use 8mm scoring wheel. its all to do with the cutting wheels. 8mm flat porc, 10mm slightly riven and 18mm for heavier riven tiles.
