Norton 78072728557 Abrasive Belt 120 Grit 3/4x20-1/2 in

Product Description

The NORTON 78072728557 is a coated abrasive belt engineered for consistent material removal on metal, fabricated parts, and hard surfaces. Built on a heavy-duty X-weight polyester cloth backing, this belt uses zirconia alumina grain in a closed-coat configuration at 120 grit (medium grade). Zirconia alumina is a self-sharpening grain that fractures under load to expose fresh cutting edges, making it well suited to aggressive stock removal and finish work on ferrous and non-ferrous metals. The closed-coat density maximizes grain coverage for fast, uniform cutting action. This belt is rated for both wet and dry operation under the R823P series designation.

This belt fits portable and stationary belt sanding machines that accept a 3/4 inch by 20-1/2 inch configuration. Typical applications include weld seam blending, deburring, edge finishing, and surface conditioning on metal workpieces. At 120 grit it bridges the gap between aggressive stock removal and final surface prep, making it a practical choice for fabrication shops, maintenance facilities, and metalworking operations that need a versatile intermediate-grit option.

Key Features

• Zirconia alumina grain fractures under load for extended belt life and consistent cut rate
• Closed-coat construction maximizes abrasive surface coverage for fast material removal
• X-weight polyester cloth backing resists tearing and flexing under high belt tension
• Rated for both wet and dry sanding applications
• 120 grit medium grade suits weld blending, deburring, and pre-finish surface prep
• R823P series construction designed for demanding metalworking environments

Compatibility

Designed for use on belt sanders and finishing machines that accept a 3/4 inch wide by 20-1/2 inch long abrasive belt. Verify machine drive and idler roller width before installation.

Installation Notes

Power down and disconnect the belt sander from its power source before changing belts. Confirm belt tracking direction arrows align with the machine's drive rotation before tensioning. Inspect the drive roller and platen for wear or debris that could cause uneven belt contact. Follow the machine manufacturer's tensioning guidelines and wear appropriate eye and hand protection during installation and operation.
