Norton 78072728901 Abrasive Belt 120 Grit 4x132 Inches

Product Description

The NORTON 78072728901 is a coated abrasive belt designed for high-stock-removal grinding and finishing applications on metal and other hard materials. Built on a heavyweight X-weight polyester cloth backing, this belt handles the tension and heat generated by aggressive belt grinder use without stretching or delaminating. Zirconia alumina grain at 120 grit (Fine grade) delivers a sharp, self-fracturing cutting action that extends belt life compared to standard aluminum oxide. Closed-coat construction maximizes grain coverage across the full belt surface for consistent cut rates. The belt measures 4 inches wide by 132 inches long and is rated for both wet and dry operation.

This belt is suited for use in metal fabrication shops, weld blending, pipe and structural steel finishing, and industrial maintenance environments. The R823P series is a workhorse choice for stationary belt grinders and wide-contact applications where a durable, aggressive-cutting fine-grit belt is needed. Wet or dry compatibility makes it adaptable to operations where coolant or cutting fluid is applied to reduce heat and improve surface finish. Fabricators, machinists, and maintenance technicians are the primary installers and users of this belt.

Key Features

• Zirconia alumina abrasive grain self-fractures during use, maintaining a sharp cutting edge and extending belt service life
• 120 grit Fine grade is appropriate for blending, light stock removal, and pre-finishing passes
• Closed-coat construction provides maximum abrasive coverage for uniform cut and consistent surface finish
• X-weight polyester cloth backing resists stretching and withstands high belt tension on stationary grinders
• Rated for both wet and dry operation, compatible with coolant-assisted grinding setups
• NORTON R823P series construction for reliable splice strength and tracking on standard belt grinder platens

Compatibility

Designed as a direct-fit replacement or standard supply belt for stationary belt grinders and finishing machines that accept a 4-inch wide by 132-inch long abrasive belt.

Installation Notes

Belt grinder installation should be performed by a qualified technician familiar with the machine manufacturer's tracking and tension procedures. Disconnect and lock out power to the grinder before changing belts. Verify belt direction-of-travel arrow aligns with wheel rotation before powering on. Inspect the contact wheel, platen, and idler for wear or damage each time a belt is replaced.
