Norton 78072727558 Abrasive Belt 120 Grit 1/2x18 in

Product Description

The NORTON 78072727558 is a coated abrasive belt designed for precision material removal on metal, wood, and composite surfaces. Built on a heavyweight X-weight rayon cloth backing, it delivers the rigidity and durability needed for demanding belt grinding and finishing applications. The belt runs 1/2 inch wide by 18 inches long and carries a 120-grit aluminum oxide abrasive in a closed-coat configuration. Aluminum oxide is a hard, sharp abrasive grain well suited to ferrous metals and hardwoods. The closed-coat density maximizes cutting surface contact, improving stock removal rates at medium grit. This belt is rated for both wet and dry operation, adding flexibility across shop environments.

This belt fits portable belt sanders and benchtop belt grinder setups that accept 1/2-inch by 18-inch belts. It is a standard choice for tool-and-die work, metal fabrication, woodworking shops, and maintenance applications where a medium-grit finish pass is required. The 120-grit rating sits in the medium grade range, making it appropriate for intermediate stock removal and surface preparation ahead of finer finishing. It is part of the Norton R283 series, a line of rayon-backed coated abrasive belts intended for general-purpose grinding and blending.
