Norton 78072731152 Abrasive Belt 180 Grit 4x36 in

Product Description

The NORTON 78072731152 is a coated abrasive belt designed for aggressive material removal and fine finishing on metal, wood, and composite surfaces. Built on a heavyweight polyester cloth backing with an X-weight designation, this belt handles the tension and heat of high-speed belt grinders and file belt machines. The abrasive material is zirconia alumina, a self-sharpening grain that maintains cut rate through extended use. At 180 grit, it falls in the very fine grade range, making it suited for final-pass surface conditioning and scratch refinement after coarser stock removal. The closed coat density ensures uniform surface contact across the full belt face.

This belt is part of the R823P series and measures 4 inches wide by 36 inches long, fitting standard 4 x 36 stationary belt sanders and portable units of the same platen size. It supports both wet and dry operation, giving technicians flexibility when working with coolant-assisted grinding setups or dry finishing applications. Typical users include metal fabricators, pipefitters, millwrights, and maintenance trades performing weld seam blending, deburring, and surface prep on ferrous and non-ferrous workpieces.

Key Features

• Zirconia alumina grain self-sharpens under pressure for sustained cut rate
• Closed coat construction delivers uniform abrasive coverage across the belt face
• X-weight polyester cloth backing resists tearing and heat buildup under load
• 180 grit very fine grade for finish passes and scratch refinement
• Compatible with both wet and dry grinding and sanding operations
• R823P series construction for consistent performance across production runs

Compatibility

Designed as a direct-fit replacement belt for stationary and portable belt sanders and grinders accepting a 4 inch by 36 inch abrasive belt.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive belt machinery. Power down and lock out the machine before changing belts. Verify belt tracking alignment and tension before resuming operation. Follow the machine manufacturer guidelines and applicable ANSI abrasive safety standards when mounting and running coated abrasive belts.
