Norton 66254457869 Abrasive Belt 40 Grit 3/4x20-1/2 in

Product Description

The NORTON 66254457869 is a coated abrasive belt built for aggressive material removal on metal and other hard surfaces. It runs on 3/4-inch-wide by 20-1/2-inch-long belt sanders and uses a zirconia alumina abrasive grain bonded to a heavyweight Y-weight polyester backing. At 40 grit, it falls in the extra coarse grade range, making it well suited for rapid stock removal, weld blending, and heavy surface conditioning. The closed coat density ensures maximum grain coverage across the belt face. It is rated for both wet and dry operation, adding flexibility across shop environments.

This belt is designed for use in industrial and trade shop settings where consistent, high-rate material removal is required. It fits 3/4-inch belt sanders that accept a 20-1/2-inch belt length. Metalworkers, fabricators, and maintenance technicians will encounter this belt on grinder and finishing setups used for deburring, seam removal, and surface prep on steel and stainless. The R887D series designation identifies this as part of a product line engineered for durability under sustained load and heat.

Installation Notes

Always power down and unplug the belt sander before changing belts. Confirm belt tracking direction matches the arrow marked on the belt backing before tensioning. Inspect the platen and contact wheel for wear before installing a new belt, as damaged contact surfaces reduce belt life and cut quality. Follow the tool manufacturer guidelines for tension and tracking adjustment.
