The saws used foe corals are the equivalent of a tile or glass saw, in other words a saw that is designed to saw with water present for cooling, something semi waterproof obviously. And as @coralreefer said you need a diamond blade. Even diamond blades seem to dull really quickly (they only seem to be good for the first five uses IME and then they’re not great tools but get the job done for another 200-400 uses until the blade snaps altogether). If someone can suggest something better than a tile saw please let me know, I’m really unhappy with my Griffin.
