I've seen videos of people cutting concrete using a circular saw and diamond blade, and using a hose on the running blade to minimize the dust. My initial reaction is how are they safely running water on a device that's plugged into an electrical outlet? The saws don't seem to be specifically designed for wet use. Are all corded circular saws able to be used in a wet application like this? Are the electrical motor components sealed and isolated from the blade or does it depend on the saw? I'd like to save money and not have to buy or rent a specialty concrete saw if possible.
I have a Porter Cable PC13CSL.
