This Blade can be used on all tile material cuts Accurately and purcisely
No, the DW4764 is for Porcelain, Granite and Slate. We do not currently manufacture a blade specifically for glass.
I have it mounted on a Harbor Freight tile-cutting saw, which is a sliding type bevel saw with water lubrication. I have that mounted on a rolling stand.
Not easily. Best bet is to pull the toilet, and put the tile underneath it - that way, no cut edges show and you'll get a better seal. All you'll need is a thicker wax ring when you re-install the toilet. Always put the flooring down first, then the cabinets, toilet, et cetera.
Depends on material cutting. I've had mine for a year cutting porcelain,ceramic,limestone,granite etc
