Norton 78072721990 Abrasive Belt 50 Grit 3/4x18 in

Product Description

The NORTON 78072721990 is a coated abrasive belt designed for dry material removal on portable and stationary belt sanders. Running 3/4 inches wide by 18 inches long, this belt uses aluminum oxide grain at 50 grit for aggressive, coarse-grade stock removal. The Series R228 construction features a closed-coat layout on an X-weight cloth backing, which provides durability under load and consistent cut rate across metal, wood, and composite surfaces. Fabricators, maintenance techs, and tool-and-die workers reach for this belt when fast material removal matters more than finish quality.

This belt is suited to portable belt sander applications where a narrow, 18-inch loop is required. The 3/4-inch width fits compact finishing tools commonly used for deburring, weld prep, surface conditioning, and edge work on metal or wood workpieces. The dry-only rating makes it appropriate for standard shop environments without coolant or water. The coarse 50-grit cut is best used early in a progression before stepping up to finer grits for finish work.

Installation Notes

Belt installation should be performed with the sander unplugged and at rest. Confirm belt tracking direction arrow aligns with sander wheel rotation before powering on. Ensure the platen or contact arm is clear of debris before seating the belt. This is a dry-use belt only and should not be used with water, cutting fluids, or coolants.
