Norton 78072753071 Abrasive Belt 36 Grit 4x54 in

Product Description

The NORTON 78072753071 is a coated abrasive belt engineered for aggressive material removal in demanding grinding and finishing applications. Built on a heavy Y-weight cloth backing, this belt carries zirconia alumina abrasive grain in a closed-coat pattern at 36 grit — a very coarse grade suited for rapid stock removal on metal, weld seams, castings, and similar hard materials. Part of the R821P series, it is designed for dry operation on stationary and portable belt grinding equipment used in fabrication, welding, and industrial maintenance.

This belt is a standard choice for metalworking shops, fabrication facilities, and maintenance technicians who need consistent, high-rate stock removal on ferrous and non-ferrous metals. The 4-inch width and 54-inch length fit a range of industrial belt grinders and combination sanders commonly found in production and job-shop environments. The zirconia alumina grain is self-sharpening under pressure, which extends belt life compared to standard aluminum oxide options in heavy grinding tasks.

Key Features

• 36 grit very coarse grade for fast, aggressive stock removal
• Zirconia alumina abrasive grain — self-sharpening under load for extended belt life
• Closed-coat construction maximizes grain coverage for consistent cut rate
• Heavy Y-weight cloth backing withstands high tension and heat in sustained grinding
• Dry operation rated — suited for metal grinding, weld blending, and surface preparation
• R821P series construction for industrial-duty belt grinder applications

Compatibility

Designed for use on belt grinders and combination sanders accepting 4-inch x 54-inch abrasive belts in dry grinding applications.

Installation Notes

Installation is typically performed by machinists, fabricators, or maintenance technicians familiar with belt grinding equipment. Power down and lockout/tagout the grinder before changing belts. Verify belt tracking direction arrow aligns with the machine drive direction before starting the grinder. Inspect the platen, contact wheel, and idler for wear or damage before mounting a new belt.
