Unless I’m drilling a large hole in ceramic tile I never drill a pilot hole first but I do know that some people advise that you do. I prefer to be very careful and start drilling very slowly to make sure that I’m on target and the bit doesn’t slip. I don’t have to buy 2 ceramic tile drill bits that way. When drilling ceramic tiles make sure that you use a power drill that has a variable speed control, which can be set to rotate very slowly.
