Dynabrade 90497 Abrasive Belt 80 Grit 1/2x34 in Aluminum Oxide

Product Description

The DYNABRADE 90497 is a coated abrasive belt designed for use with narrow belt sanders and file belt tools in metalworking, woodworking, and finishing applications. Measuring 0.5 inches wide by 34 inches long, this belt uses aluminum oxide abrasive on an X-weight cloth backing, delivering consistent cut and durability across both dry and wet operations. The 80-grit medium grade makes it well suited for stock removal, weld blending, and surface preparation tasks where a balance between aggression and finish quality is needed. Trades professionals and fabricators reach for this belt when working in tight areas or on contoured surfaces that standard wider belts cannot reach.

This belt is a practical choice for portable file belt sanders commonly used in metal fabrication shops, maintenance and repair operations, and light industrial environments. The X-weight cloth backing provides flexibility for contour work while maintaining enough rigidity for flat stock passes. Wet or dry operation capability gives the installer flexibility when working with cutting fluids or running dry on ferrous and non-ferrous metals. Individual unit packaging makes it easy to stock in small quantities or add to a tool kit for field service work.

Installation Notes

Installation is typically performed by the operator prior to use and requires no special tools beyond the belt tensioning mechanism built into the tool. Ensure the tool is disconnected from its power or air supply before changing the belt. Thread the belt over the drive and idler wheels with the arrow on the belt backing aligned to the intended direction of travel if marked. Inspect the belt for tears or loose splice joints before starting the tool.
