In numerous sanding discs, some of them can be divided into dry and wet sandpaper. So what's the difference between dry and wet sandpaper?

Wet sandpaper is small and its grinding chippings is also small. If we use sandpaper and water together, the chippings can flow out by following the water. So, it is better to use with water. And it is very convenient to use dry sandpaper. Because of its larger gap between sand, the chippings will fall off in the process of grinding, so it is better not to use with water.
