Norton 78072722400 Abrasive Belt 40 Grit 4x132 in

Product Description

The NORTON 78072722400 is a coated abrasive belt designed for heavy stock removal on metal, wood, and composite surfaces. Built on a heavyweight X-weight cloth backing, this belt runs dry and delivers consistent cutting action across its full 4-inch by 132-inch contact area. The 40-grit aluminum oxide abrasive is closed-coat and rated coarse grade, making it well suited for aggressive grinding, weld blending, and surface preparation tasks. Fabricators, metalworkers, and woodworkers use belts in this size class on large stationary or floor-standing belt grinders and sanders where belt life and cut rate matter most.

This belt fits wide-format belt grinders and finishing machines that accept 4-inch by 132-inch belts. It is commonly used in fabrication shops, millwork operations, and industrial maintenance settings where coarse-grade material removal is required. The dry-operation rating means it is not suitable for wet grinding setups. The R228 series designation identifies the product family within the NORTON coated abrasives line.

Installation Notes

Belt installation should be performed by a qualified operator following the machine manufacturer's guidelines. Power down and lock out the machine before changing belts. Confirm correct belt tracking and tension before resuming operation, and inspect the belt for cracks or separation at the splice joint prior to use.
