Norton 78072721992 Abrasive Belt 150 Grit 3.5x15.5 in

Product Description

The NORTON 78072721992 is a coated abrasive belt designed for dry grinding, finishing, and surface preparation on a belt sander. Running on aluminum oxide abrasive grain at 150 grit, this belt falls in the very fine grade range, making it well-suited for final-pass material removal, smoothing, and light stock removal on metal, wood, and composite surfaces. The belt measures 3.5 inches wide by 15.5 inches long and features a heavy-duty X-weight cloth backing with a closed coat density for consistent, even cutting action across the full belt surface. It is sold as a single unit.

This belt is intended for use in shop and trade environments where a portable or stationary belt sander requires a reliable replacement abrasive. At 150 grit very fine grade, it is typically used in the latter stages of surface finishing — after coarser grits have removed bulk material — to achieve a smooth, refined surface. It is appropriate for metal fabrication shops, woodworking operations, and general maintenance applications. The dry-only operation designation means it should not be used with water, cutting fluids, or lubricants.

Key Features

• 150 grit very fine grade aluminum oxide abrasive for controlled material removal and smooth finishing
• Closed coat density delivers uniform cutting action and consistent surface finish
• X-weight cloth backing provides durability and flexibility under load
• Dry operation design — compatible with standard belt sander use without coolant or fluid
• Series R228 construction for repeatable performance across replacement belts

Compatibility

Designed as a replacement coated abrasive belt for belt sanders accepting a 3.5-inch by 15.5-inch belt. Verify sander model specifications before installation to confirm belt size fitment.

Installation Notes

Belt installation should be performed with the sander powered off and unplugged. Verify the directional arrow on the belt backing aligns with the sander drive direction before tensioning. Inspect the platen and drive roller for wear or debris before mounting a new belt. Follow all applicable shop safety practices, including use of eye protection and dust collection, during abrasive operations.
