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.
