Dynabrade 90354 Abrasive Belt 80 Grit 3-1/2 X 15-1/2 in

Product Description

The DYNABRADE 90354 is a coated abrasive belt designed for use with compatible belt sanders and finishing tools in metalworking, fabrication, and surface preparation applications. Measuring 3.5 inches wide by 15.5 inches long, the belt uses aluminum oxide abrasive grain at 80 grit, placing it in the medium grade range suited for stock removal and surface blending. The cloth backing carries an X-weight designation, indicating a durable, flexible substrate that holds up under both dry and wet operating conditions. Licensed tradespeople and fabricators rely on this belt for consistent cut rate and grain durability across steel, aluminum, and other common workpiece materials.

This belt is intended for use in industrial and professional shop environments where belt sanders require a medium-cut abrasive for weld blending, deburring, and general surface conditioning. Its wet or dry compatibility makes it suitable for applications where coolant or water is used to control heat and extend abrasive life. The 3.5-inch by 15.5-inch format fits specific benchtop and handheld belt sanders that accept this belt size. Fabricators, pipefitters, and metalworking professionals are the primary installers and end users of this consumable.

Installation Notes

Belt replacement is a routine consumable swap performed by the tool operator. Power down and disconnect the tool from its power source before removing or installing an abrasive belt. Ensure the belt is seated correctly on the drive and idler rollers with the arrow or seam direction aligned to tool rotation before resuming operation. Inspect the belt for tears or edge damage before each use and discard worn belts promptly to avoid inconsistent finish results.
