     · 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.
