Tru-maxx 7221 Abrasive Belt 40 Grit 3x24 in Aluminum Oxide

Product Description

The TRU-MAXX 7221 is a coated abrasive belt designed for aggressive material removal on belt sanders and similar stationary or handheld abrasive machines. Built around aluminum oxide grain in a coarse 40-grit configuration, it cuts quickly through wood, metal, and composite surfaces. The closed-coat construction packs abrasive grain tightly across the polyester cloth backing, delivering consistent scratch patterns and extended cut life compared to open-coat alternatives. The X-weight polyester cloth backing provides high tensile strength and resistance to tearing under load, making this belt a dependable choice for heavy stock removal tasks in shop and field environments.

This belt is suited for dry sanding and grinding applications in woodworking shops, metal fabrication, and general manufacturing environments. The 3-inch by 24-inch format is a common size for bench-top belt sanders used by machinists, carpenters, welders, and maintenance technicians. At 40 grit, it is primarily used for shaping, deburring, weld blending, and rapid surface preparation before moving to finer abrasive stages. Sold individually, it fits workflows where single-belt replacement or mixed-grit setups are standard practice.

Key Features

• 40-grit coarse aluminum oxide grain for fast, aggressive stock removal
• Closed-coat construction maximizes grain coverage for consistent cutting action
• X-weight polyester cloth backing resists tearing and flexing under load
• Dry-use rated — not intended for wet sanding applications
• 3 x 24 inch format fits a wide range of standard bench-top belt sanders

Compatibility

Designed as a direct-fit replacement for 3 x 24 inch belt sander machines requiring coarse-grit abrasive belts in standard shop and industrial configurations.

Installation Notes

Belt sanders must be powered off and unplugged before changing abrasive belts. Verify belt tension and tracking adjustment after installation and before powering the machine. Wear appropriate eye and hand protection during belt changes and operation. Follow shop safety procedures and any applicable OSHA guidelines for abrasive equipment use.
