Norton 78072727578 Abrasive Belt 100 Grit 1x30 in Aluminum Oxide

Product Description

The NORTON 78072727578 is a coated abrasive belt designed for precision grinding and finishing on metal, wood, and composite surfaces. Built on an X-weight rayon cloth backing, this belt delivers durability and flexibility through tight radius work and high-contact-pressure applications. The aluminum oxide grain is applied at closed coat density across a 1 inch wide by 30 inch long profile, producing consistent material removal at 100 grit. At a Fine grade, it is suited for finishing passes and surface prep where a smooth, uniform finish is required. This belt is rated for both wet and dry operation, making it adaptable across a wide range of grinding setups.

This abrasive belt is used in portable belt sanders, bench-mounted file belt machines, and narrow belt finishing units common in metal fabrication shops, HVAC sheet metal work, plumbing rough-in prep, and general maintenance applications. The 1 inch by 30 inch format is a standard size for compact inline and handheld belt tools. The Fine 100-grit designation makes it appropriate for deburring, weld blending, and pre-finish surface conditioning on ferrous and non-ferrous metals.

Installation Notes

Installation is performed by qualified operators familiar with portable or bench-mounted abrasive belt equipment. Disconnect the tool from its power source before changing belts. Verify belt tracking direction against the arrow marked on the belt backing before seating the belt on the drive and idler rollers. Inspect the platen, rollers, and tension mechanism for wear before fitting a new belt.
