i never realized they wernt, I have got a plasplugs wet cutter bought it 10 yrs ago or so its so tiny you can just get a 6" wide tile fully on the deck. Its got a tiny diamond wheel and its great for kitchens as its so small, great for 100x100mm and mosaics and it keeps all the water in side it with no overspray. sits on the work top so neat you forget its there and because its so small its great for doing plunge cuts for sockets etc..
