Norton 66261002321 Abrasive Belt 80 Grit 4x36 Aluminum Oxide

Product Description

The NORTON 66261002321 is an aluminum oxide abrasive belt designed for surface preparation and finishing work across metal, wood, and composite materials. Part of the Rapid Prep series, this belt measures 4 inches wide by 36 inches long and cuts at 80 grit, placing it in the medium grade range. The non-woven construction backed by polyester cloth delivers consistent abrasion with controlled flexibility, making it suitable for blending, deburring, and light stock removal. It supports both wet and dry operation, giving technicians flexibility depending on the application and workpiece requirements. Fabricators, maintenance techs, and metalworkers are the primary users.

This belt fits standard 4 x 36 inch belt sanders and grinders common in fabrication shops, HVAC sheet metal work, plumbing rough-in prep, and general maintenance environments. The medium grit rating makes it appropriate for intermediate surface conditioning after coarser cutting passes or before moving to finer finishing grits. Wet or dry compatibility broadens its use across both ferrous and non-ferrous substrates where coolant or lubricant is preferred.

Installation Notes

Abrasive belts should be installed by trained personnel familiar with the sander or grinder manufacturer guidelines. Confirm belt tracking and tension before powering the machine, and verify the arrow on the belt backing aligns with the direction of rotation if marked. Wear appropriate PPE including eye protection and gloves during installation and operation. Inspect the belt for tears or delamination before each use.
