Norton 78072727559 Abrasive Belt 80 Grit 1/2x18 in

Product Description

The NORTON 78072727559 is a coated abrasive belt designed for aggressive material removal in grinding, finishing, and surface preparation applications. Built on an X-weight rayon cloth backing, this belt handles both wet and dry operation without losing structural integrity. It measures 0.5 inches wide by 18 inches in length and carries an 80-grit aluminum oxide abrasive in a closed-coat configuration. The closed coat delivers consistent scratch patterns and efficient stock removal on metal, wood, and composite surfaces. Machinists, fabricators, and finishing technicians working with belt grinders and file belt machines will find this a dependable production-grade consumable.

This belt fits standard 0.5-inch by 18-inch belt grinder and file belt machine platens used in metalworking shops, maintenance facilities, and fabrication environments. The 80-grit coarse rating makes it well suited for weld blending, deburring, edge breaking, and initial surface conditioning on ferrous and non-ferrous metals. The aluminum oxide abrasive performs reliably across repeated passes and tolerates the heat generated during dry grinding. The wet/dry rating also makes it usable in applications where coolant or water is introduced to control heat or improve surface finish quality.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with abrasive belt equipment. Always power down and de-energize the machine before changing belts. Inspect the drive wheel, idler, and platen for wear or damage prior to mounting a new belt. Ensure belt tracking is adjusted correctly before resuming operation to prevent edge damage or premature failure.
