Norton 78072791744 Abrasive Belt 180 Grit 2x42 in Aluminum Oxide

Product Description

The NORTON 78072791744 is a coated abrasive belt designed for dry grinding, blending, and finishing applications on metal, wood, and composite surfaces. Part of the R228 series, it measures 2 inches wide by 42 inches long and carries a 180-grit aluminum oxide abrasive on a closed-coat, X-weight polyester cloth backing. The closed-coat construction provides consistent cut and finish across the belt face. At 180 grit, this belt falls in the fine grade range, making it suited for finish work, surface prep, and light stock removal. Machinists, fabricators, and woodworkers install these belts on standard 2 x 42 inch belt grinders and sanders.

This belt is used in both metalworking and woodworking shops where a fine finish pass or pre-polish surface condition is required. The aluminum oxide abrasive holds up well on ferrous and non-ferrous metals, hardwoods, and engineered wood products. The X-weight polyester cloth backing resists tearing under moderate tension and heat, making it reliable for sustained dry-grinding operations on bench-top and pedestal belt grinders. This is a dry-use-only belt and is not rated for wet grinding applications.

Installation Notes

Belt installation should be performed by a qualified machinist or tool operator following the machine manufacturer's guidelines. Power down and disconnect the grinder from its power source before changing belts. Confirm belt tracking alignment before resuming operation, and verify the belt arrow or direction marking, if present, matches the machine's direction of travel. Eye protection and appropriate PPE should be worn during operation and belt changes.
