IMO it is nothing to do with the cutter, its the tile in most cases
I agree, there are the odd few tiles that just won't cut, usually those stupid double fired ones. Do they not realise it just makes them brittle and a pain to cut? Over engineered for no good reason.
They are a nightmare! Very frustrating, the wheel on the cutter is fine, I think it's the density and how they have been made.
I know this is an old thread, but just to chime in... I have a big clinker that I've put a brand new wheel on. Having the exact same problem with the porcelain tiles I'm currently laying, which is why I'm now using a wet cutter for everything. My big clinker was mostly trouble free when I did porcelain tiles 6+ years ago in my old kitchen - the tiles were cheap ones off eBay then too, the current ones are relatively expensive.

My clinker was doing great, cutting with light pressure score and breaking very cleanly then suddenly it started chipping the glaze? bits popping off after its scored? heavier pressure is slightly better but its still popping off in places. These will look bad when I grout. tried various adjustments and 2 new wheels but no joy. Any ideas?
A wet/dry porcelain blade in a 4inch grinder 95% of the time ,only ever doing wet cuts on external corners and window cuts ?
