3x21 inch Sanding Belts, 15 Pack 40/80/120/240/400 Grit for Belt Sander

Key features

• [15-Piece Complete Set] 3x21 belt sander sanding belts — 3 each of 40, 80, 120, 240 and 400 grit. Strip, shape, smooth and finish without stopping to reorder. These 3 x 21 inch (75 x 533 mm) belts fit most standard 3x21 belt sanders
• [Color-Coded by Grit] Grab the right belt in one glance — no flipping belts over to read the back. Five colors map to five grits from coarse 40 to fine 400, so you swap belts faster and never load the wrong grit mid-job
• [Seamless Flat Joint] The flat, dual-direction joint forms a smooth seam with no bump or snag — run the belt either way. Backed by a tear-resistant cloth that holds tension under load instead of fraying apart
• [Cuts Cooler, Lasts Longer] Premium aluminum oxide grain bonded with high-strength phenolic resin resists loading and heat buildup, so belts cut cooler, hold their edge and sand through more material before swapping
• [Wood, Metal, Plastic & More] From woodworking to knife and tool sharpening — use these belts for wood, metal grinding and deburring, paint and rust removal, and plastic. Fit most handheld and benchtop 3x21 belt sanders for DIY projects and professional workshops
