Norton 78072727937 Abrasive Belt 40 Grit 3x24 in

Product Description

The NORTON 78072727937 is a coated abrasive belt designed for aggressive material removal on metal, wood, and composite surfaces. Running on belt sanders and grinding machines, this belt features aluminum oxide abrasive in a 40-grit, extra coarse grade — suited for rapid stock removal, weld grinding, and surface prep work. The closed-coat construction keeps abrasive grain densely packed across the full belt face, maximizing cut rate. An X-weight cloth backing provides the rigidity and tear resistance required for demanding production and jobsite use. Installation requires no tools beyond the sanding machine itself.

This belt measures 3 inches wide and 24 inches long, fitting a wide range of portable and stationary belt sander platforms used in metalworking, fabrication shops, and construction trades. The dry-use aluminum oxide grain performs well on ferrous and non-ferrous metals, hardwoods, and painted or primed surfaces. The Series R228 designation identifies this as a Norton industrial coated abrasive product. Typical users include metal fabricators, pipefitters, ironworkers, and general tradespeople performing weld cleanup, deburring, or aggressive surface conditioning.

Installation Notes

Power down and unplug the belt sander or disconnect it from its power source before changing the belt. Confirm belt tracking direction — most abrasive belts have a recommended run direction marked on the backing. Seat the belt fully onto the drive and idler rollers, then adjust the tracking knob before powering the unit back on. Inspect the belt for tears or separation before each use; do not run a damaged belt.
