When sanding wood, the amount of material removed depends on a few factors, including the type of sander and grit used. Generally speaking, sanders with coarser grits (such as 40-grit sandpaper) will remove more material than finer grits (like 220-grit sandpaper). Other factors that can affect how much wood is removed when sanding include:
- The speed of the sander.
- The pressure of the person doing the sanding.
- The type of wood being sanded.
In general, sanding wood with a belt or drum sander will remove more material than sanding by hand.
