Norton 78072727762 Abrasive Belt 40 Grit 6x60 Zirconia Alumina

Product Description

The NORTON 78072727762 is a coated abrasive belt designed for aggressive material removal on metal, weld seams, and fabricated workpieces. Built on a polyester cloth backing, it handles the flex and tension demands of wide-belt and contact-wheel grinding applications. The zirconia alumina grain is self-sharpening under pressure, which sustains cut rate as the belt wears. At 40 grit, this is an extra-coarse belt suited for stock removal, deburring, and surface preparation ahead of finer finishing passes. The closed coat density maximizes grain coverage for fast, consistent cuts. This belt is rated for dry use only and runs in Norton Series R821P.

This belt fits wide-belt sanders, floor grinders, and industrial finishing machines configured for a 6-inch by 60-inch belt. It is a standard selection in metal fabrication shops, structural steel work, and heavy-duty grinding operations where aggressive cutting action is needed before progressing to intermediate grits. Welding shops and pipe fabricators commonly use 40-grit zirconia belts for initial weld blending and scale removal. Licensed fabricators and industrial maintenance trades install and operate belts of this type.

Key Features

• Zirconia alumina grain self-sharpens under grinding pressure for sustained cut rate
• 40 grit extra-coarse grade for heavy stock removal and weld blending
• Closed coat density delivers maximum grain coverage and fast cutting action
• Polyester cloth backing resists tearing and handles flex on contact-wheel machines
• Dry-use construction — not rated for wet or coolant-assisted grinding
• Norton Series R821P designation for consistent lot-to-lot specification

Compatibility

Designed for wide-belt sanders and contact-wheel grinders that accept a 6-inch by 60-inch abrasive belt in dry grinding applications.

Installation Notes

Abrasive belts of this size are typically installed and operated by trained fabricators or industrial machine operators. Before changing a belt, power down the machine and allow all moving parts to come to a complete stop. Confirm belt tracking alignment after installation and run the machine briefly at operating speed before applying workpiece contact. Do not use this belt with liquid coolants or in wet grinding setups.
