Dynabrade 90258 Abrasive Belt 3/4 X 18 in Aluminum Oxide

Product Description

The DYNABRADE 90258 is a non-woven abrasive belt designed for precision surface finishing on metal, wood, and composite materials. Built with aluminum oxide abrasive on a scrim backing, it delivers consistent cut and finish at a very fine grade. The belt measures 3/4 inches wide by 18 inches long, fitting compact belt sanders and inline finishing tools common in fabrication and maintenance work. It supports both wet and dry operation, making it adaptable to a range of finishing environments. Metalworkers, fabricators, and maintenance technicians typically use this belt for light stock removal, blending, and surface preparation.

This belt is suited for light deburring, weld blending, surface conditioning, and pre-finishing operations. The very fine grade is appropriate for final-pass work where surface consistency matters, such as preparing a surface for coating or achieving a uniform scratch pattern. Its compact 3/4-inch by 18-inch profile fits narrow-contact belt tools commonly used in tight or contoured areas. Wet and dry compatibility expands its use across both dry grinding setups and wet finishing processes in shop environments.
