Dynabrade 89242 Abrasive Belt 3-1/2 X 15-1/2 in Medium

Product Description

The DYNABRADE 89242 is a medium-grade, non-woven aluminum oxide abrasive belt designed for surface finishing, blending, and deburring applications. Built on a scrim backing, this belt delivers consistent cut and finish performance across both wet and dry operating conditions. At 3-1/2 inches wide and 15-1/2 inches in overall length, it fits compact and handheld belt finishing tools common in metal fabrication, maintenance, and industrial service environments. Technicians and tradespeople reach for this belt when a controlled, uniform surface profile is the goal rather than aggressive stock removal.

This belt is suited for use on metal, composite, and similar hard surfaces where blending welds, smoothing rough edges, or preparing surfaces for coating are the primary tasks. The non-woven aluminum oxide construction conforms to irregular contours better than coated abrasive belts, making it a practical choice for finishing inside corners, curved profiles, and joint areas. Both wet and dry operation is supported, giving the installer flexibility depending on the workpiece material and shop conditions.

Installation Notes

Install and replace abrasive belts with the tool fully powered down and disconnected from its air or electrical source. Verify belt tracking and tension before resuming operation according to the tool manufacturer guidelines. Inspect the belt for tears or fraying before each use and replace if damaged. Eye protection and appropriate respiratory protection should be worn during abrasive finishing work.
