Norton 78072721308 Abrasive Belt 320 Grit 2x72 in

Product Description

The NORTON 78072721308 is a coated abrasive belt designed for dry grinding, blending, and finishing operations on belt sanders and similar power abrasive equipment. It measures 2 inches wide by 72 inches in overall length and carries a 320 grit aluminum oxide abrasive, placing it in the extra fine grade range. The aluminum oxide grain is bonded in a closed coat pattern to a polyester cloth backing with an X-weight designation, providing firm support and resistance to flex fatigue during continuous use. Licensed HVAC, plumbing, and mechanical tradespeople as well as metalworking shops use extra fine belts like this for final surface prep, deburring, and light material removal.

This belt is suited for dry-only operation on stationary or portable belt sander setups where a 2 inch by 72 inch format is required. The closed coat, X-weight polyester backing makes it appropriate for ferrous and non-ferrous metals, wood composites, and similar substrate finishing tasks. Its extra fine 320 grit rating targets finish passes rather than aggressive stock removal, making it a common choice at the tail end of a multi-grit progression in fabrication and maintenance environments.

Key Features

• 320 grit extra fine aluminum oxide abrasive for finish-stage material removal and surface prep
• Closed coat construction maximizes abrasive coverage across the belt face
• X-weight polyester cloth backing delivers stiffness and durability under continuous belt sander loads
• Dry-only rated operation — do not use with water-based or oil-based coolants
• Series R228 designation for accurate replacement and reorder identification
• Sold individually — package quantity of 1 belt per order unit

Compatibility

Designed as a replacement or stock belt for belt sanders and power abrasive machines that accept a 2 inch by 72 inch abrasive belt format with dry operating conditions.

Installation Notes

Belt installation should be performed with the sander unplugged or locked out per standard OSHA lockout/tagout procedures. Verify belt tracking and tension according to the equipment manufacturer guidelines before resuming operation. Inspect the belt for tears or edge fraying before each use, and never run a damaged belt. This product is rated for dry use only — exposure to coolants or moisture will degrade the bond and backing.
