3M 7100141440 Abrasive Belt 60 Grit 24x1/4 Inch Aluminum Oxide

Product Description

The 3M 7100141440 is a general-purpose aluminum oxide abrasive belt designed for metal deburring, general metalworking, and woodworking applications. The 384F series features an XF-weight polyester cloth backing that holds up under both wet and dry conditions, making it suitable for demanding grinding and heavy sanding tasks. At 60 grit, this belt removes material efficiently on mild steel, carbon steel, aluminum, bronze, and brass. The resin bond system handles high heat and pressure, extending belt life during aggressive use. Licensed tradespeople and fabricators rely on this belt for consistent cut rates across a wide range of substrates.

This belt is sized at 24 inches in length and 1/4 inch in width, making it appropriate for narrow-contact backstand and benchtop belt sanders. It is also well suited for stroke sanding, portable belt grinding, and wide belt grinding and finishing operations. The aluminum oxide mineral performs reliably on mild and carbon steel as the primary target metals, with effective results on softer metals including aluminum, bronze, and brass. Its maroon cloth construction is a standard identifier for the 384F product family within the 3M abrasives line.

Installation Notes

A licensed fabricator or metalworking technician should install and replace abrasive belts following the equipment manufacturer's belt-change procedures. Always power down and lock out the sanding or grinding machine before changing the belt. Confirm belt travel direction arrows align with machine rotation before resuming operation. Inspect the platen, idler, and drive rollers for wear or debris prior to installation.
