Norton 78072727587 Abrasive Belt 80 Grit Aluminum Oxide R283

Product Description

The NORTON 78072727587 is a coated abrasive belt engineered for consistent stock removal and surface finishing in both wet and dry grinding applications. Built on an X-weight rayon cloth backing with a closed-coat aluminum oxide abrasive layer, this belt delivers durable cutting action at an 80 grit medium grade. The heavy backing resists tearing under load, making it well suited for sustained belt sander use on metal, wood, and composite materials. At 1-1/2 inches wide and 18-15/16 inches long, it fits compact file belt sanders and detail grinders commonly used by fabricators, machinists, and finishing tradespeople.

This belt is designed for workshop and light industrial environments where controlled material removal and smooth surface preparation are required. The R283 series construction combines the durability of rayon cloth with aluminum oxide abrasive, a combination suited to ferrous and non-ferrous metals as well as hardwoods. Wet or dry operation is supported, giving technicians flexibility when working with coolant-assisted grinding setups or standard dry finishing operations. The closed-coat density maximizes abrasive coverage per square inch, reducing loading on softer materials.

Key Features

• 80 grit medium grade for aggressive stock removal and surface leveling
• Aluminum oxide abrasive provides long-lasting cut on metal and wood
• X-weight rayon cloth backing resists flex fatigue and tearing under belt tension
• Closed-coat construction maximizes abrasive density across the belt surface
• Supports both wet and dry grinding operations
• R283 series construction for consistent performance across the belt run

Compatibility

Designed as an OEM-style replacement or standard consumable for belt sanders and file sanders accepting a 1-1/2 inch by 18-15/16 inch abrasive belt.

Installation Notes

Install with the belt tracking arrow aligned to the direction of travel before tensioning the sander drive. Power down and disconnect the tool from its power source before changing belts. Inspect the platen and drive roller for debris or wear before seating a new belt. Closed-coat belts can load quickly on resinous or soft materials — keep a belt cleaning stick on hand to extend belt life.
