Fine
Pre-stain hardwoods. Soft enough not to leave swirls.
What 180 grit is for
180-grit is the lower end of pre-finish grits. It removes 120-grit scratches cleanly and leaves a surface ready to receive stain or sealer on hardwood. For softwoods, 180 is often the highest grit needed before finish.

Abrasive materials
Common mistake
On open-grain hardwoods (oak, ash, walnut), 180 may still feel rough — push to 220 if the stain finish needs to read smooth.
