Dynabrade 90355 Abrasive Belt 120 Grit 3-1/2 X 15-1/2 in

Product Description

The DYNABRADE 90355 is a coated abrasive belt engineered for use with compatible belt files and narrow-belt sanders in metalworking, fabrication, and finishing applications. It measures 3.5 inches wide by 15.5 inches in overall length and carries a 120-grit aluminum oxide abrasive bonded to an X-weight cloth backing. The X-weight cloth provides durability and resistance to tearing under moderate-to-heavy contact pressure. At 120 grit, this belt falls in the fine grade range, making it well suited for surface blending, finish work, and light stock removal on metal, wood, and composite materials. It supports both wet and dry operation.

This belt is intended for use in shop environments where precision finishing is required. Typical applications include weld blending, edge deburring, and surface preparation on metal components. The wet-dry capability allows use with water or cutting fluids to reduce heat buildup and extend belt life during extended runs. Fabricators, maintenance technicians, and tool-and-die professionals commonly use belts of this type with handheld belt files or stationary narrow-belt grinders.

Key Features

• 120-grit aluminum oxide abrasive for fine-grade finishing and light stock removal
• X-weight cloth backing resists tearing and handles contact pressure in demanding applications
• Wet and dry operation compatible for use with or without cutting fluids

Compatibility

Designed as a replacement or consumable abrasive belt for narrow-belt sanders and belt files requiring a 3.5 x 15.5 inch belt size. Verify tool belt-size specifications before ordering.

Installation Notes

Abrasive belt replacement should be performed with the tool disconnected from its power source or air supply. Ensure the belt tracking is adjusted correctly before resuming operation to prevent premature edge wear or belt failure. Follow the tool manufacturer guidelines for belt tension and tracking adjustment. Inspect the platen and drive components for wear before installing a new belt.
