Norton 78072726320 Abrasive Belt 320 Grit 3x132 in Aluminum Oxide

Product Description

The NORTON 78072726320 is a coated abrasive belt designed for precision dry grinding, finishing, and surface preparation on stationary or portable belt sanders. Built on a Series R245 polyester cloth backing with a J-weight flexibility rating, it delivers consistent cut and durability across metal and wood applications. The abrasive mineral is aluminum oxide in an extra fine 320 grit with a closed coat density, producing smooth, refined surface finishes on the final passes of a sanding or grinding operation. At 3 inches wide and 132 inches long, this belt fits a range of industrial and shop-grade machine configurations.

This belt is suited for dry-only operation in metalworking, woodworking, and fabrication environments where a controlled, fine finish is required. The 320 grit extra fine classification makes it appropriate for finish work after coarser material removal stages have been completed. The closed coat construction maximizes abrasive surface coverage, which helps maintain a consistent scratch pattern on flat or contoured workpieces. Typical users include machinists, welders, metalworkers, and finish carpenters running wide or long-platen belt sanding equipment.

Key Features

• 320 grit extra fine aluminum oxide abrasive for smooth, refined finish passes
• Series R245 polyester cloth backing with J-weight for flexibility and tensile strength
• Closed coat density maximizes abrasive coverage and produces a consistent scratch pattern
• Dry-only operation keeps mineral bond integrity intact throughout the belt life

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive belt for stationary and portable belt sanders accepting a 3 x 132 inch belt configuration.

Installation Notes

Installation is performed by machinists or shop technicians familiar with belt sander equipment. Power down and lock out the machine before removing the worn belt and seating the replacement. Verify belt tracking alignment before resuming operation, as a misaligned belt can edge-wear rapidly or contact the machine housing. This belt is rated for dry use only — do not apply cutting fluids or water during operation.
