WebJun 29, 2024 · A low grain size number indicates large grit, and a high number indicates a small grain. Grain sizes are broadly defined as coarse (6 to 24), medium (30 to 60), fine (70 to 180), and very fine (220 to 1,000.) Very fine grits are used for polishing and lapping operations, fine grains for fine-finish and small-diameter grinding operations.
