Dynabrade 90338 Abrasive Belt 220 Grit Aluminum Oxide

Product Description

The DYNABRADE 90338 is a coated abrasive belt designed for precision surface finishing on metal, wood, and composite materials. Measuring 3.5 inches wide by 15.5 inches long, it uses aluminum oxide abrasive grain bonded to a heavy-duty cloth backing rated X-weight for rigidity and durability under load. At 220 grit, this belt falls in the very fine grade range, making it well suited for final-pass finishing, blending, and light stock removal where surface quality matters. Both wet and dry operation are supported, giving technicians flexibility based on the application and material requirements.

This belt is appropriate for use in industrial, metalworking, fabrication, and maintenance environments. The 3.5 x 15.5 inch size fits compatible inline and right-angle belt sanders used in tight spaces or contoured surface work. Very fine 220 grit makes it a go-to choice for finishing passes on stainless steel, aluminum, mild steel, and hardwood. Wet operation capability allows use with cutting fluids or water to reduce heat buildup and extend belt life on heat-sensitive materials.

Installation Notes

Abrasive belts should be installed by the operator per the tool manufacturer's belt-change procedure. Power down and disconnect the sander from its air or electrical supply before changing belts. Confirm belt tracking and tension after installation before resuming operation. Inspect the belt for tears or separation before each use and replace if damage is found.
