Every grit you could need is included in this bargain box of Klingspor industrial sanding belts. At this low price you'd think these are cheapo belts that won't hold up under normal sanding pressure. Wrong. These are the same premium quality, heavy cloth backed, butt joined, resin coated, aluminum oxide belts we sell individually. Each box contains 6 sleeves of belts in the following grits: 1 sleeve 180-240 (fine), 2 sleeves 120-150 (med-fine), 2 sleeves 80-100 (medium), and 1 sleeve 50-60 (coarse). Depending on the size, there are either 5 or 6 belts per sleeve.
