Norton 78072721880 Abrasive Belt 80 Grit 3x132 in

Product Description

The NORTON 78072721880 is a coated abrasive belt designed for aggressive material removal on stationary and portable belt sanders. Built on an X-weight cloth backing for rigidity and tear resistance, this belt carries a closed-coat layer of aluminum oxide grain at 80 grit — a coarse cut suited for stock removal, weld blending, rough shaping, and surface preparation on metal, wood, and composites. At 3 inches wide and 132 inches in overall length, the belt fits longer-platen industrial machines. It is rated for dry operation only and is part of the NORTON R228 series.

This belt is a practical choice for fabrication shops, millwork operations, and maintenance technicians who need consistent, high-removal abrasive performance on wide-format belt sanding equipment. The aluminum oxide abrasive self-sharpens under pressure, extending usable belt life during coarse grinding and blending passes. The 80-grit cut is appropriate as a first-stage pass before stepping up to finer grits for finish work.

Key Features

• 80 grit coarse aluminum oxide abrasive for fast stock removal
• Closed-coat grain pattern maximizes cutting surface contact
• X-weight cloth backing resists flexing and tearing under load
• Dry-use rated — not suitable for wet grinding applications
• R228 series construction for consistent grain adhesion and belt strength
• 3 inches x 132 inches size fits long-platen industrial belt sanders

Compatibility

Designed as a replacement or consumable abrasive belt for industrial and commercial belt sanding machines that accept 3-inch wide by 132-inch long belts with standard butt-spliced or lap-spliced joints.

Installation Notes

Abrasive belt installation should be performed by a qualified operator following the machine manufacturer's belt-tracking and tensioning procedures. Power down and lock out the sanding machine before removing the spent belt and seating the replacement. Confirm the arrow printed on the belt backing aligns with the machine's direction of rotation before re-energizing. Inspect the belt for cracks, delamination, or splice separation before each use and discard any belt showing signs of damage.
