3M 7100231078 Abrasive Belt 80 Grit 4x24 in Aluminum Oxide

Product Description

The 3M 7100231078 is a coated abrasive belt designed for aggressive material removal in grinding, blending, and finishing applications. Built on a heavy-duty X-weight cloth backing, it carries an open-coat aluminum oxide abrasive at 80 grit, placing it in the medium grade range. The open-coat construction reduces loading and heat buildup, keeping the belt cutting freely across metal, wood, and composite surfaces. At 4 inches wide and 24 inches long, it fits standard belt grinders and sanders used daily in fabrication, maintenance, and finishing shops. Dry operation only. Installation and use require no special tooling beyond a compatible machine.

This belt is suited to metal fabrication shops, woodworking operations, and general industrial maintenance environments. The 80-grit aluminum oxide abrasive handles stock removal, weld blending, and surface prep tasks where a medium cut rate is needed before moving to finer finishing stages. The cloth backing withstands the tension and flex demands of high-speed belt machines. It is a single-use consumable supplied one belt per package.

Installation Notes

A licensed or qualified technician or machine operator should confirm belt tracking and tension settings match the machine manufacturer specifications before running. Power down and de-energize the belt sander or grinder completely before mounting or removing the belt. Inspect the belt for tears, edge damage, or splice separation prior to each use. Do not use this belt in wet or coolant-flooded conditions.
