Product Description

The 3M 7100141284 is an aluminum oxide cloth-backed abrasive belt designed for general-purpose metalworking and woodworking tasks. Measuring 18 inches in length and 3/4 inch in width, this P320 grit belt features an XF-weight polyester cloth backing bonded with a resin system rated for high heat and pressure. The aluminum oxide mineral delivers consistent stock removal across a broad range of substrates. It is well suited for metal deburring, surface finishing, and general sanding work performed by machinists, fabricators, and maintenance tradespeople.

This belt is optimized for use on mild steel and carbon steel and is also effective on softer metals including aluminum, bronze, and brass. It handles both wet and dry operating conditions thanks to its waterproof polyester backing. Suitable equipment includes backstand or benchtop belt sanders, stroke sanders, portable belt grinders, and wide belt grinding and finishing machines. The maroon cloth backing is a standard identifier for this product line within the 3M 384F series.
