2SAND 3x21 Aluminum Oxide Sanding Belts

3″ x 21″ Aluminum Oxide Sanding Belts – X-Weight Cloth

2SAND’s 3 x 21 aluminum oxide sanding belts are designed for the most common portable belt sander size on the market. Aluminum oxide grain on X-weight cloth backing delivers fast stock removal on wood, metal, and plastics with a backing heavy enough to resist tearing under sustained load. Resin-over-resin bond keeps the grain secure through long runs.

Why Choose These Belts?

• Aluminum oxide abrasive – Self-sharpening mineral that maintains a consistent cut rate across many common materials.
• X-weight cloth backing – Durable polyester/cotton blend handles high tension and elevated temperatures without delaminating.
• Resin-over-resin bond – Extended grain retention means more linear feet of sanding per belt.
• Broad grit range – Covers coarse material removal through fine finishing in a single product line.
• Made in the USA – Fabricated to order from domestic jumbo roll stock.

Ideal Applications

• Portable 3″ x 21″ belt sanders (Makita, DeWalt, Bosch, and others)
• Hardwood and softwood stock removal and leveling
• Paint and coating removal from metal
• Weld bead blending
• Edge shaping on lumber and sheet goods
