Norton 78072728550 Abrasive Belt 120 Grit Zirconia Alumina

Product Description

The NORTON 78072728550 is a coated abrasive belt designed for precision grinding and finishing on metal, wood, and composite surfaces. Built on a polyester cloth backing with X-weight construction, it delivers consistent stock removal and finish quality under both wet and dry operating conditions. The belt measures 0.25 inches wide by 24 inches long and runs 120 grit zirconia alumina abrasive in a closed-coat configuration. Zirconia alumina is a self-sharpening abrasive grain well suited to aggressive material removal on ferrous metals, stainless steel, and hard alloys. This belt is part of the R823P series and is installed by machinists, fabricators, and tool-and-die professionals on narrow belt grinders and file belt machines.

This belt is sized for narrow-profile belt grinders, die grinders with belt attachments, and precision file belt tools commonly used in metal fabrication shops, maintenance facilities, and production grinding applications. The 0.25-inch width makes it suitable for contour work, deburring, and weld blending in tight or hard-to-reach areas. The closed-coat, X-weight polyester cloth backing resists tearing under tension and handles the heat generated during aggressive grinding passes. Wet or dry operation gives the technician flexibility in application depending on the material and finish requirement.

Key Features

• Zirconia alumina abrasive grain — self-sharpening for extended belt life on hard metals
• 120 grit for controlled material removal and smooth intermediate finishing
• Closed-coat construction maximizes abrasive surface coverage for consistent cut
• X-weight polyester cloth backing resists stretch and heat under load
• Compatible with wet or dry grinding and finishing operations
• Narrow 0.25-inch by 24-inch profile fits file belt machines and die grinder attachments

Compatibility

Designed as a direct-fit replacement belt for narrow belt grinders and file belt machines accepting a 0.25-inch by 24-inch abrasive belt. Confirm machine contact wheel and platen dimensions before installation.

Installation Notes

Installation is performed by machinists or fabricators familiar with abrasive belt equipment. Disconnect and lock out power to the machine before changing belts. Verify belt tracking and tension per the machine manufacturer's guidelines before resuming operation. Inspect the contact wheel or platen for wear or damage prior to mounting a new belt, as irregular surfaces reduce belt life and cutting consistency.
