Norton 78072721900 Abrasive Belt 36 Grit 3x132 in

Product Description

The NORTON 78072721900 is a coated abrasive belt designed for aggressive material removal in industrial and trade grinding, blending, and surface prep applications. Built on an X-weight cloth backing, this belt handles the mechanical stress of high-pressure belt grinder and sander work without tearing or stretching. At 36 grit, it falls in the extra coarse range, making it the right choice for rapid stock removal, weld seam grinding, scale removal, and rough shaping on metal or wood. Closed coat density maximizes cutting contact across the full belt surface. The belt measures 3 inches wide by 132 inches in overall length and operates dry only.

This belt suits fabrication shops, pipefitters, ironworkers, millwrights, and general metalworking trades running stationary or portable belt grinders. The 132-inch length fits longer-platen machines common in industrial settings. The 36-grit aluminum oxide abrasive cuts through mild steel, stainless, cast iron, and hardwood efficiently. It is part of the NORTON R228 series, a closed-coat aluminum oxide line engineered for consistent cut rate across the belt life. Typical use cases include weld prep, deburring, and rough shaping before progression to finer grits.

Installation Notes

Belt installation should be performed by qualified personnel familiar with abrasive grinding equipment. Power down and lock out the machine before changing the belt. Verify the arrow or directional marking on the belt aligns with the machine drive direction before tensioning. Inspect the platen, contact wheel, and tracking guides for wear or damage prior to running a new belt.
