Norton 78072750279 Abrasive Belt 80 Grit 4x132 Zirconia

Product Description

The NORTON 78072750279 is a coated abrasive belt designed for heavy-duty material removal on metal, stainless steel, and other demanding work surfaces. Built on a durable polyester backing with a closed-coat zirconia alumina abrasive, this belt delivers consistent cut rate and long service life under both wet and dry operating conditions. At 80 grit, it sits in the coarse range, making it well suited for aggressive stock removal, weld blending, and surface conditioning tasks. It measures 4 inches wide by 132 inches long, fitting stationary belt grinders and wide-platen machines common in fabrication and industrial maintenance environments.

This belt is intended for use on stationary belt grinding equipment sized for 4-inch by 132-inch media. The zirconia alumina grain self-sharpens during use, which sustains cut rate over the life of the belt and reduces the frequency of belt changes in high-volume grinding operations. Typical applications include weld seam removal, deburring, and rough surface preparation on carbon steel, stainless steel, and other ferrous and non-ferrous metals. It is commonly used by metal fabricators, maintenance technicians, and industrial grinding operators working with wide-belt or drum-type grinding machines.

Key Features

• Zirconia alumina abrasive grain provides aggressive, self-sharpening cut for extended belt life
• Closed-coat construction maximizes grain coverage for faster stock removal
• Polyester backing resists tearing and flexing under high-tension grinding conditions
• Rated for both wet and dry operation, compatible with coolant-assisted grinding setups
• 80 grit coarse grade suited for weld blending, deburring, and rough surface prep
• Series R884P construction balances flexibility and durability for production grinding environments

Compatibility

Designed to fit stationary belt grinding machines that accept 4-inch by 132-inch abrasive belts. Verify platen size, contact wheel diameter, and belt tension specifications on your equipment before installation.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive belt grinding equipment. Power down and lock out the machine before changing belts. Confirm belt tracking direction matches the arrow marked on the belt backing before tensioning. Inspect the contact wheel and platen for wear or damage prior to installing a new belt.
