8" x 3" 280 Grit Resin Bonded Diamond Sanding Belts – Precision Grinding & Polishing Belts for Stone, Glass & Metal

Our 8" × 3" Resin Bonded Diamond Sanding Belt (3" × 25-7/32") bridges coarse grinding and fine smoothing across an extra-wide surface area on expandable rubber drum wheels and upright belt sanders. Engineered with 280 grit diamond abrasives securely held in a resilient resin matrix, it rapidly erases harsh scratches left by coarser grits and establishes smooth, uniform surfaces across gemstones, mineral slabs, and glass edges.
