3M 7100231493 Abrasive Belt 80 Grit 37x75 in Aluminum Oxide

Product Description

The 3M 7100231493 is a coated abrasive belt designed for heavy-duty dry grinding, blending, and surface preparation on metal, wood, and composite materials. Built on a heavy X-weight cloth backing, it runs in the 340D series and delivers consistent 80-grit, medium-grade stock removal across wide-belt machine applications. The open-coat aluminum oxide construction resists loading and maintains cut rate over extended use. At 37 inches wide by 75 inches long, this belt fits large-format wide-belt sanders and grinders common in fabrication shops and industrial finishing lines.

This belt is suited for stationary wide-belt sanding machines used in metal fabrication, woodworking production lines, and industrial surface conditioning. Its 80-grit medium grade makes it a first-pass or intermediate cut belt, appropriate for removing mill scale, weld spatter, machining marks, or rough surface texture before finer finishing steps. Dry operation only. Typical users include metal fabricators, millwork shops, and industrial maintenance trades running large-format belt equipment.

Installation Notes

Belt installation should be performed by qualified equipment operators following the machine manufacturer's tensioning and tracking procedures. Power down and lockout the machine fully before changing belts. Inspect the belt for tears, splice integrity, and correct running direction arrow orientation before starting the machine. Always use appropriate eye and respiratory protection when operating coated abrasive equipment.
