Norton 78072727957 Abrasive Belt 120 Grit 4x36 Aluminum Oxide

Product Description

The NORTON 78072727957 is a coated abrasive belt engineered for dry material removal on stationary and portable belt sanders. Part of the R228 series, it measures 4 inches wide by 36 inches long and runs 120 grit aluminum oxide abrasive on a heavy-duty X-weight cloth backing. The closed-coat construction delivers consistent, uniform scratch patterns with minimal loading, making it well-suited for intermediate finishing passes on metal, wood, and composite surfaces. Licensed trades and skilled fabricators rely on this belt for its durability and predictable cut rate across extended sanding cycles.

This belt is designed for dry operation and fits standard 4 by 36 inch belt sanders used in metal fabrication shops, woodworking operations, and general maintenance environments. The R228 series targets medium-duty applications where surface preparation or intermediate finishing is required before final-grit work. Its X-weight cloth backing handles the flex and tension demands of continuous-run machines without tearing or tracking issues.

Installation Notes

Disconnect the belt sander from power before changing belts. Confirm the belt tracking arrow matches the direction of sander rotation before tensioning. Ensure the platen and idler roller are free of debris that could cause the belt to track off-center or tear prematurely. This product is for dry use only — do not introduce water, cutting fluid, or coolant during operation.
