Norton 78072723195 Abrasive Belt 40 Grit 4x36 in

Product Description

The NORTON 78072723195 is a coated abrasive belt designed for aggressive material removal on metal, weld seams, and hard surfaces. Built on a heavyweight Y-weight cloth backing, it runs in the Series R821P line and uses zirconia alumina grain in a closed-coat configuration. The 40-grit coarse grade delivers fast stock removal and handles high-pressure applications where cut rate matters more than surface finish. It is a dry-operation belt suited for stationary belt grinders and portable belt sanders used by metal fabricators, pipefitters, and maintenance technicians.

This belt is sized at 4 inches wide by 36 inches long, fitting standard 4 x 36 belt grinder machines common in fabrication shops and field maintenance setups. The zirconia alumina abrasive self-sharpens under pressure, extending usable life compared to aluminum oxide belts at similar grit levels. Closed-coat density means the abrasive covers the full backing surface, maximizing cut efficiency on ferrous metals, stainless steel, and hard alloys.

Key Features

• Zirconia alumina grain self-sharpens under load for sustained cut rate
• 40-grit coarse grade optimized for rapid stock removal and weld grinding
• Closed-coat construction maximizes abrasive coverage across the full belt surface
• Heavyweight Y-weight cloth backing resists tearing under high-tension operation
• Dry-operation design for use on standard belt grinders and portable sanders
• Series R821P construction for consistent performance across belt-to-belt use

Compatibility

Designed as an OEM-style replacement or standard consumable for belt grinders and portable belt sanders accepting 4 x 36 inch abrasive belts.

Installation Notes

Installation should be performed by a qualified metal fabricator or maintenance technician familiar with belt grinder operation. Power down and disconnect the machine from its power source before changing belts. Verify belt tracking and tension per the machine manufacturer's guidelines before resuming operation. Do not exceed the maximum operating speed rated for the belt or grinder.
