Hi Gary the Rubi rep here.
I have seen one of these blades break like those two and was curious as to why. I have used these blades alot and have not had any bother with them so I asked the end user to demonstrate how he was using the blade. One week later I met Darren on site. I gave him a grinder and a brand new blade and he set to work. Darren proceeded to try and cut curves in his porca and you could see the blade bending. I have done more test on my own and established that this blade cut perfect when the blade is held vertically. I don't know if that is the reason why they broke but you have to remember the blades are thin. Hope to get more feedback as and when.

Hi Gary, i have since been informed that these blades are part of Rubi's budget range and just to add the blade was not used under stress as it was a straight cut.

My take on it is!!!.. with these being on the low quality side to what Rubi top range is, the steel of the blade cannot take a lot of heat generated by dry cutting grade 5 porcs, yes the diamonds might cut great but if the body of the blade and also that the blade flange is thin then this contributes to blade warping and hence the break away just below the diamond segments each time of the 2 breakages i have had.

I have given the blades to rubi but as present have yet to hear anything back from Pat..

I have had the same problems with marcrist blades i kid you not, chunks come out of them too.
I'm using a tectron blade from stonetools at the minute and it's been great, 1mm thick and i'v done a lot of cutting with it over the last few weeks.
I find it wearing down now at the tip but no chipping as yet or bits breaking off.
Cheap blade too but impressive cutting.
Jury still out on mine.

Just bumping some of the tiling tool review threads in the main tiling tools forum. Ignore this if it's an old one and not important to you. It'll soon drop off the list.
