Norton 78072728617 Abrasive Belt 100 Grit 2x48 in

Product Description

The NORTON 78072728617 is a coated abrasive belt designed for aggressive material removal and finishing on metal, wood, and composite surfaces. Built on a heavy-duty X-weight polyester cloth backing, this belt handles the stress of high-pressure belt grinding and sanding applications. It measures 2 inches wide by 48 inches long and cuts at 100 grit, placing it in the medium-grade range for controlled stock removal and surface blending. The zirconia alumina abrasive grain is self-sharpening under pressure, extending belt life compared to standard aluminum oxide alternatives. Closed-coat construction keeps grain density high for consistent cut rates across the belt surface.

This belt is suited for stationary and portable belt sanders used in metal fabrication shops, maintenance and repair operations, and general industrial finishing. It supports both wet and dry operation, making it compatible with machines that use coolant or water to manage heat and workpiece distortion. Trades including pipefitters, ironworkers, welders, and general maintenance technicians commonly use this belt size for weld seam blending, deburring, and surface prep before coating or inspection.

• X-weight polyester cloth backing resists tearing and flexing under load
• Closed-coat construction delivers consistent cut rate and surface finish
• Supports wet and dry operation for versatile machine compatibility
• 100 grit medium grade balances stock removal with surface smoothness
• Series R823P formulation optimized for ferrous and non-ferrous metal grinding

Compatibility

Designed as an OEM-style replacement abrasive belt for belt sanders and grinders accepting a 2-inch by 48-inch belt configuration in industrial and maintenance applications.

Installation Notes

Belt installation should be performed with the machine powered off and unplugged or locked out per OSHA lockout/tagout procedures. Verify belt tracking and tension after installation and before resuming operation. Inspect the platen and contact wheel for wear that could cause uneven belt loading or premature failure. Replace the belt if visible cracking, edge fraying, or backing separation is observed.
