Tru-maxx 7273 Abrasive Belt 50 Grit 4x36 in Aluminum Oxide

Product Description

The TRU-MAXX 7273 is a coated abrasive belt designed for aggressive material removal on belt sanders and stationary grinding equipment. Running at 50 grit, this is a coarse-grade belt suited for rapid stock removal, weld dressing, rust elimination, and surface prep on metal, wood, and composite materials. The abrasive material is aluminum oxide, one of the most widely used minerals in industrial abrasives for its durability and consistent cut rate. The belt measures 4 inches wide by 36 inches long and is built on a polyester cloth backing with an X-weight designation, indicating a heavy, tear-resistant construction appropriate for demanding shop environments.

This belt is intended for dry-operation belt sanding applications in fabrication shops, maintenance departments, and trade service settings. The closed-coat abrasive density means the aluminum oxide grains cover the full surface area of the backing, maximizing cutting efficiency per pass. It is commonly used by metalworkers, pipefitters, welders, and millwrights for prep work ahead of coating or inspection. Woodworkers and general contractors also reach for 50-grit belts when leveling rough stock or removing old finishes quickly.

Installation Notes

Disconnect and lock out power to the sander before changing belts. Confirm the belt tracking direction arrow aligns with the machine rotation direction before reinstalling the guard and resuming operation. Inspect the platen and drive rollers for wear or debris that could cause uneven belt contact. Wear appropriate PPE including eye protection and gloves when handling and installing abrasive belts.
