If you've got a belt sander that uses 2-inch by 72-inch belts, this 7-pack assortment is a lifesaver for your workshop. You get one belt of each of the most useful grits: 40 (coarse), 60, 80, 120, 180, 240, and 400 (fine). That covers you from heavy-duty material removal all the way to final smoothing and finishing. The belts are made with tough, open-coat aluminum oxide grain bonded with a strong resin-on-resin system. This means they resist loading up (clogging) with material, last a long time, and can even be washed if needed. They're also heat and moisture resistant, with a smooth, firm splice that won't catch or bump during sanding. Perfect for working on wood, aluminum, fiberglass, plastic, and non-ferrous metals. Whether you're shaping a table, smoothing a weld, or prepping a surface for paint, having this range of grits on hand means you're always ready for the next step. Stock up and make your sanding jobs quicker and smoother!
