Norton 78072728639 Abrasive Belt 120 Grit 2x72 in Zirconia

Product Description

The NORTON 78072728639 is a coated abrasive belt designed for aggressive material removal and finishing on metal, wood, and composite surfaces. Built on a polyester cloth backing with X-weight designation, this belt delivers the flexibility and tensile strength needed for demanding belt grinding and sanding applications. The abrasive is zirconia alumina in a closed-coat configuration at 120 grit, rated as a medium grade. At 2 inches wide and 72 inches long, it fits a wide range of stationary and portable belt grinders used in fabrication, maintenance, and production environments. Licensed trades and industrial technicians rely on this belt series for consistent cut rate and extended service life.

This belt is suited for use on stationary belt grinders, slack-belt machines, and portable belt sanding tools configured for a 2-inch by 72-inch belt path. The R823P series with closed-coat zirconia alumina is commonly applied to ferrous metals, stainless steel, aluminum, and hardwoods. It supports both wet and dry operation, making it adaptable to coolant-assisted grinding setups as well as dry material removal. Typical users include metal fabricators, maintenance mechanics, and production grinders working in shop and field environments.

Installation Notes

Installation should be performed by a qualified technician familiar with belt grinder machinery. Power down and lockout the machine before changing belts. Verify belt tracking and tension per the machine manufacturer's guidelines before resuming operation. Inspect the contact wheel, platen, and idler for wear or damage that could cause premature belt failure.
