Norton 78072721250 Abrasive Belt 40 Grit 2x48 in

Product Description

The NORTON 78072721250 is a coated abrasive belt designed for aggressive stock removal on metal, wood, and composite surfaces. Running 2 inches wide by 48 inches long, this belt uses aluminum oxide grain in a closed-coat configuration on an X-weight cloth backing. At 40 grit, it sits in the extra coarse range, making it well suited for rapid material removal, weld blending, and surface prep before finer finishing passes. Licensed machinists, fabricators, and metalworkers are the primary users. It is rated for dry operation only and belongs to NORTON's R228 series, which is built around durability under sustained belt-grinder loads.

This belt fits standard 2 x 48 inch belt grinders and bench-top belt sanders commonly found in fabrication shops, maintenance facilities, and production environments. The R228 series is engineered for ferrous and non-ferrous metal grinding as well as hardwood shaping. It is a strong choice for deburring, scale removal, and initial stock reduction ahead of intermediate and finish grit sequences. Because of its extra coarse designation, it is typically the first belt in a multi-stage finishing workflow rather than a final-pass abrasive.

Key Features

• 40 grit extra coarse aluminum oxide grain for fast, aggressive stock removal
• Closed-coat configuration maximizes grain coverage for consistent cut rate
• X-weight cloth backing resists tearing and flex fatigue under sustained belt-grinder loads
• Dry-use rated for standard bench and floor-mount belt grinder applications
• R228 series construction balances cut speed with belt life on metal and wood substrates

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive for belt grinders and belt sanders requiring a 2 x 48 inch coated abrasive belt.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians. Power down and disconnect the grinder or sander from its power source before changing belts. Confirm belt tracking alignment and tension per the machine manufacturer's guidelines before resuming operation. Wear appropriate PPE including eye protection and gloves when handling abrasive belts and during grinding operations.
