Dynabrade 91438 Abrasive Belt 80 Grit 1/2x24 in Aluminum Oxide

Product Description

The DYNABRADE 91438 is a coated abrasive belt designed for use with narrow belt file sanders and detail grinding tools. It measures 0.5 inches wide by 24 inches long and carries an 80-grit aluminum oxide abrasive on a cloth backing with an X-weight rating. The medium grit makes it well-suited for general-purpose stock removal, weld blending, and surface preparation on metal, wood, and composites. Both wet and dry operation are supported, giving technicians flexibility depending on workpiece material and finish requirements. Machinists, fabricators, and finishing tradespeople are the typical installers and users of this belt type.

This abrasive belt fits narrow file belt sanders and pencil grinders with a 0.5-inch by 24-inch belt path. It is commonly used in production and maintenance environments for deburring, edge blending, and contour finishing on tight radii and hard-to-reach surfaces. The 80-grit aluminum oxide cuts aggressively enough for initial material removal while leaving a surface ready for finer finishing passes. Wet or dry compatibility makes it adaptable for both metalworking and woodworking applications on the shop floor or in the field.

Installation Notes

Installation is performed by machinists or finishing technicians using standard belt sander tool-change procedures.

Inspect the backing for tears or edge damage before each use.
