Norton 78072732289 Abrasive Belt 80 Grit 3/4x18 in

Product Description

The NORTON 78072732289 is a coated abrasive belt designed for aggressive material removal on a variety of surfaces. Part of the R283 series, this belt uses aluminum oxide abrasive grain on an X-weight rayon cloth backing with a closed coat density, making it well suited for heavy stock removal and finishing tasks. The belt measures 3/4 inches wide by 18 inches long and operates at 80 grit, which falls in the coarse grade range. It supports both wet and dry operation, giving technicians and fabricators flexibility in how they run it. Total unit weight is 0.05 pounds.

This belt fits portable and bench-mounted belt sanders commonly used in metalworking, woodworking, and general fabrication shops. The 3/4 x 18 inch format is a standard size used on many handheld file belt sanders and small stationary units. Coarse 80 grit is appropriate for initial shaping, weld blending, rust removal, and rapid surface conditioning. The wet/dry rating allows use with water or light cutting fluids, which helps extend belt life and manage heat on metal substrates.

Installation Notes

Belt sanders should be powered off and unplugged before changing abrasive belts. Confirm the drive and idler roller width matches the 3/4 inch belt width before installation. Ensure the belt is oriented with the arrow or seam lap running in the direction of travel to prevent premature separation. Inspect tracking alignment after installation and adjust before resuming operation.
