Dynabrade 91166 Abrasive Belt 80 Grit 1/2 X 13 Inches

Product Description

The DYNABRADE 91166 is a coated abrasive belt designed for use with compatible narrow-belt file sanders and finishing tools. It measures 1/2 inch wide by 13 inches long and runs at 80 grit, placing it in the medium grade range. The belt uses aluminum oxide abrasive grain bonded to an X-weight cloth backing, which provides durability and flexibility during aggressive stock removal or surface preparation work. It supports both dry and wet operation, giving technicians flexibility depending on the application. This belt is a consumable item sold individually, with a minimum order quantity of 50 units.

This belt is suited for metalworking, fabrication, and maintenance applications where a narrow-profile belt tool is required to reach confined or contoured areas. The 80-grit medium grade makes it appropriate for initial surface conditioning, weld blending, deburring, and general material removal on metal, wood, or composite surfaces. It is commonly used by industrial maintenance technicians, pipefitters, fabricators, and metalworkers who require consistent abrasive performance in tight spaces.
