3M 7100122771 Abrasive Belt 18x0.5 Inch 60 Grit Aluminum Oxide

Product Description

The 3M 7100122771 is an aluminum oxide cloth-backed abrasive belt designed for general-purpose metalworking, metal deburring, and woodworking tasks. Built on an XF-weight polyester cloth backing, this belt handles heavy grinding and sanding loads in both wet and dry conditions. The resin bond resists high heat and pressure, keeping the abrasive mineral in place during demanding passes. At 60 grit, it removes material aggressively while still leaving a workable surface finish. The aluminum oxide mineral provides consistent cut rates across a wide range of substrates without loading quickly.

This belt is well suited for use on backstand and benchtop belt sanders, stroke sanders, portable belt grinders, and wide belt grinding and finishing machines. It performs best on mild steel and carbon steel, and is also effective on softer metals including aluminum, bronze, and brass. The waterproof polyester backing extends belt life in wet grinding setups, making it practical for shops that use coolant or water during metal finishing operations.
