Selectively tbh. For marble and stone its amazing. But or 6x300 porcelain you have to cut from each end to stop it chipping. Whereas an overhead cutter you can line the tile up and away you go.
For cutting long tiles though its limited by what you can hold, I cut down a quartz top 2.5m long!
That's impressive.I have just bought a rubi DC250, cut's 1200mm not even plugged it in yet, I will do a review on here when i have given it some stick.
