Brice,I remember reading somewhere, maybe with this group, that Festool does make a saw to use with masonry.
I would not, personally, use my AFT 55, or one of the TS 55/75 for cutting masonry. Cement dust can make short work of a good saw.
For years, i used fiber blades to cut all sorts of brick/block/stone/concrete. eventually, i was introduced to diamond blades and never looked back. For many uses over long periods of time, even tho original cost was greater, they were much less expense for the long haul. And they cut better with somewhat less dust. (with either type blade, there was a ton of dust. to say there was less dust might just be a case of wishful thinking) The only problem with the diamond blades was that I had to be more careful in making curved cuts. Possible, but with care. The fiber blades were a little more forgiving there.
I never kept track of the hours on a blade. With the fiber blades, I never went on a job without several backup blades. My tol box was full of half used blanks. With diamond blades, one blade would last for many jobs. I would only get a backup when the blade being used seemed to be cutting slower. I don't think I ever wore one out to point it was unusable.
