Klingspor 302879 3″ x 18″ LS 309 XH 80 Grit Cotton Back Sanding Belt (Wood & Metal)

Klingspor 302879 3″ x 18″ LS 309 XH 80 Grit Cotton-Back Sanding Belt (Wood & Metal)

Designed for both woodworking and metalworking, the Klingspor 302879 LS 309 XH sanding belt is a durable, cloth-backed 3″ x 18″ belt that delivers consistent stock removal and a clean finish on hardwoods, softwoods, steel, and non-ferrous metals. The LS 309 XH uses an aluminum oxide grain with a close coat and a resin-over-resin bond to hold up under continuous use on portable 3 x 18 belt sanders. The X-weight cotton backing adds stability for flat sanding, beveling, and edge work while maintaining flexibility for curved surfaces.

With an 80 grit cut, this belt hits the sweet spot for general sanding and intermediate surface prep—aggressive enough to level seams and remove mill marks, but fine enough to leave a uniform scratch pattern for follow-up grits or finishing passes. A precision F4G butt joint tracks smoothly and reduces chatter, helping users get predictable results on jobsite tasks, shop projects, and maintenance work.

Why Customers Choose the Klingspor  3″ x 18″ LS 309 XH 80 Grit Cotton Back Sanding Belt (Wood & Metal)

Installers and fabricators choose the Klingspor LS 309 XH 80 grit sanding belt because it delivers predictable cutting speed and a consistent scratch on a standard 3 x 18 belt sander. The aluminum oxide grain and close-coat layout help remove stock quickly during wood sanding and blend edges during light metal finishing without frequent belt swaps. With an X-weight cloth-backed belt, tracking stays stable under pressure, which means fewer marks and less rework before moving to finer grits. For mixed shops that move between steel, aluminum, and hardwood, a universal sanding belt simplifies ordering and keeps projects on schedule.
