Norton 78072728568 Abrasive Belt 80 Grit 1/2x18 in

Product Description

The NORTON 78072728568 is a coated abrasive belt engineered for aggressive material removal on metal, weld seams, and hard surfaces. Part of the R823P series, it features zirconia alumina grain on a heavy-duty polyester cloth backing with an X-weight rating, giving it the flexibility and durability needed for portable belt sander and stationary grinder applications. At 80 grit, it falls in the coarse range, making it suitable for rapid stock removal, deburring, and blending operations. A closed-coat construction packs the abrasive grain tightly across the belt face for consistent cut rate. The belt supports both wet and dry operation, allowing it to be used with coolant or dry depending on the workpiece material and surface finish requirements.

This belt is sized at 1/2 inch wide by 18 inches long, a common dimension for file belt sanders and narrow-contact-wheel grinders used in metal fabrication shops, maintenance and repair operations, and tool-and-die environments. It is typically installed by machinists, fabricators, and maintenance technicians working on ferrous and non-ferrous metals. The coarse 80 grit makes it a go-to choice when the priority is fast material removal rather than fine finishing. Wet operation capability also makes it useful in applications where heat buildup or surface contamination must be controlled.

Key Features

• 80 grit coarse grade for fast stock removal and aggressive blending
• Zirconia alumina abrasive grain delivers high cut rate and extended belt life
• Closed-coat construction provides consistent abrasive coverage across the full belt surface
• X-weight polyester cloth backing resists tearing and conforms well under load
• Wet and dry operation compatible for flexible use across workpiece types
• R823P series construction built for portable and stationary belt grinding equipment

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive belt for portable file belt sanders and stationary narrow-contact-wheel grinders that accept 1/2 inch by 18 inch belts.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians. Always power down and disconnect the tool from its power source before changing the belt. Verify the belt is seated properly on the drive and idler wheels with the arrow on the belt backing aligned to the direction of travel before resuming operation. Inspect the platen, contact wheel, and tracking adjustment before running the new belt to confirm proper tension and alignment.
