Norton 78072722773 Abrasive Belt 100 Grit 8x107 in

Product Description

The NORTON 78072722773 is a coated abrasive belt engineered for dry grinding, blending, and finishing applications on stationary belt sanding equipment. It measures 8 inches wide by 107 inches long and runs 100 grit aluminum oxide abrasive on a heavy-duty X-weight cloth backing. The closed-coat construction keeps abrasive grain tightly packed across the belt surface, producing consistent material removal and a uniform finish on metal, wood, and composite substrates. The R228 series designation identifies this belt within NORTON's standard industrial cloth belt line. Machinists, metal fabricators, and finishing tradespeople typically install this belt on wide-contact-wheel or platen-style belt grinders found in shop environments.

This belt is suited for aggressive stock removal and intermediate finishing passes where a fine 100 grit scratch pattern is the target. The aluminum oxide abrasive is a general-purpose mineral appropriate for ferrous metals, non-ferrous alloys, and hardwoods. The X-weight cloth backing resists tearing under high-pressure platen contact and tolerates the flex demands of contact-wheel operation. Dry operation is specified; this belt is not rated for wet or coolant-flood use. It is sold individually and is appropriate for shops running 8-inch-wide belt grinding or sanding machines.

Key Features

• 100 grit aluminum oxide abrasive delivers fine-grade stock removal and surface blending
• Closed-coat construction provides dense grain coverage for consistent cut rate
• X-weight cloth backing resists tearing under platen and contact-wheel pressure
• R228 series coated belt rated for dry operation only
• 8 inches x 107 inches format fits wide-belt stationary grinders and sanders

Compatibility

Designed as a replacement coated abrasive belt for stationary belt grinders and wide-belt sanders requiring an 8-inch by 107-inch belt in 100 grit. Verify machine belt size specifications before installation.

Installation Notes

Installation is performed by machinists or maintenance personnel familiar with belt grinding equipment. Power down and lock out the machine before removing the worn belt or threading the new one. Confirm belt tracking adjustment and tensioner setting before running the machine under load. Inspect the belt for tears or splice separation before each use; a damaged belt on a high-speed machine is a serious safety hazard.
