I used a passel of abrasive wheels to cut a stack of ceramic tiles. For some reason, a standard tile cutter absolutely refused to cut these particular tiles without shattering them into many pieces.
Anyway, aside from making a bunch of dust and having to replace the wheel about every ten tiles, all went as expected. For your project, the wheels are probably cheap enough to experiment.
