Norton 78072721055 Abrasive Belt 40 Grit 1-1/2x60 in

Product Description

The NORTON 78072721055 is a coated abrasive belt designed for dry grinding and stock-removal applications on metal, wood, and composite materials. Built on a heavy-duty X-weight cloth backing, it uses closed-coat aluminum oxide abrasive at 40 grit — a coarse grade suited for aggressive material removal and surface shaping. The belt measures 1.5 inches wide and 60 inches long, fitting standard belt grinders and linishing machines in that size range. It is part of the NORTON R228 series, engineered for consistent cut rate and long belt life under sustained pressure. Metalworkers, fabricators, and finishing technicians are the primary installers and end users.

This belt is used in industrial and shop environments where fast stock removal is the priority. The 40-grit coarse grade makes it well suited for weld blending, edge deburring, and initial surface prep before stepping up to finer grits. The closed-coat construction keeps abrasive grain density high across the full belt surface, delivering uniform cutting action from start to finish. Dry-operation rating means it is not intended for use with coolant or water. Typical applications include metal fabrication shops, woodworking operations, and maintenance departments that run continuous belt sanders or bench grinders with a belt attachment.

Installation Notes

Abrasive belt replacement is typically performed by the machine operator or a maintenance technician. Before changing the belt, power down and lock out the grinder per OSHA lockout/tagout procedures. Verify belt tracking alignment after installation and run the machine briefly at low load to confirm the belt seats evenly on the contact wheel and platen. Do not exceed the machine manufacturer's rated surface speed for the belt width and backing weight in use.
