Why is sandpaper grade low?
A low grade number indicates that there are bigger pieces in the blade , while a higher one means more small ones. Many sandpaper manufacturers do not specify sandpaper grade, only sand paper grit. The reason for this is that sandpaper grade cannot be specified without knowing the sanding surface's (wood, metal etc.) inherent hardness. This is because fine particles easily wear out and fall off in harder materials, while a coarse sandpaper can stand up to tougher resistance better. For example, using 100 grit sandpaper on wood will take longer than it would if 120 were used instead, since the higher number denotes more sanding power which helps remove material quicker.
What Is Sandpaper Grit?
Sandpaper grit is the standard way to measure how rough or smooth a piece of sandpaper is. Essentially, it tells you how coarse or fine that particular sheet is.

The higher the number, typically means that it will cut faster and last longer - but not always. For instance, if you're using a coarse sandpaper on wood then a lower grit might work better because it won't take off too much of your material when you go over an area.
