"Grit" as a numerical term typically refers to a measure of abrasive coarseness in materials such as sandpaper or grinding wheels. The numerical "grit" value indicates the size of the abrasive particles:

• Lower grit numbers (e.g., 40, 60) indicate coarser abrasives, which are better for removing material quickly and for rough shaping.
• Higher grit numbers (e.g., 220, 400, 1000) indicate finer abrasives, used for polishing or achieving a smooth finish.

Approximate particle size:
• 40 grit: ~425 microns
• 400 grit: ~38 microns
• 1000 grit: ~9 microns
