Dynabrade 90433 Abrasive Belt 0.25x24 in Aluminum Oxide

Product Description

The DYNABRADE 90433 is a narrow abrasive belt designed for detail sanding, deburring, and surface finishing in tight or contoured areas. Measuring 0.25 inches wide and 24 inches long, this belt fits compact file-style sanders and pencil grinders used in metalworking, woodworking, and fabrication shops. The aluminum oxide abrasive material delivers consistent cutting action across a medium grade, making it well suited for stock removal and intermediate surface prep. A non-woven construction over scrim backing provides conformability and durability through both wet and dry operation cycles. Licensed trades and production machinists typically reach for this belt when working in confined grooves, weld seams, or radiused profiles.

This belt is appropriate for light to medium material removal on metal, wood, and composite surfaces where a standard wide belt cannot reach. The non-woven aluminum oxide construction performs in wet or dry conditions, making it usable with coolant-assisted grinding setups as well as dry hand-held file belts. It is sold individually and is typically stocked in multiples for production or maintenance environments where belt turnover is frequent. Shop fitters, tool and die technicians, and metal fabricators are the primary users of this format.

Installation Notes

Installation of abrasive file belts should be performed with the tool unplugged or air supply disconnected. Verify belt tracking and tension per the tool manufacturer guidelines before applying the belt to a workpiece. Inspect the belt and drive components for wear before each use. Operate at the speed rating appropriate for the belt width and abrasive type to avoid premature failure.
