Just by looking at them, it's enough to make you want to buy them. They give you the feeling that they can pierce even through stone.

3/5.
However, I rate strictly. Firstly, it is Bosch, the same factory as Diablo. (See AvantiPro) I would expect it to be something similar. Secondly, the price is average. I would prefer to pay double the money but have it perform twice as well, in order to give it a 5/5 rating. I haven't tried it on glass, as I have special blades for glass, more "lite" ones. It cuts through plain tiles easily. However, it takes a long time to cut through ceramic tiles and those marble/granite tiles. A lot of time. Of course, at low speeds and after it cuts through the top layer, you have to switch to a different blade to reach the tile adhesive and continue from there to the cement. Unfortunately, I don't have anything better to recommend in the Greek market. I have tried different ones. I will go with this one and see. I would appreciate it if someone could suggest an alternative product.
