3M 7010326490 Abrasive Belt 40 Grit 21x3 Inch Aluminum Oxide

Product Description

The 3M 7010326490 is an aluminum oxide cloth abrasive belt designed for metal deburring, general metalworking, and woodworking applications. This 341D series belt measures 21 inches in length and 3 inches in width with a 40 grit abrasive rating, making it well suited for aggressive material removal. The X-weight cloth backing handles heavy sanding and grinding loads without tearing. A resin bond system resists high heat and pressure during continuous use. Licensed tradespeople and fabricators working on metal substrates or wood surfaces reach for this belt when they need fast-cutting, consistent performance across a range of portable and stationary sanding setups.

This belt is designed for wide belt sanding machines, edge sanders, and portable belt sanders. Its tube-shaped band profile fits both inner and outer contours, allowing it to remove parting lines, surface imperfections, and burrs from metal parts. It can also be mounted onto a rubber expander wheel attachment used with a die grinder or rotary drill for inline deburring work. The 40 grit cut rate makes it appropriate for initial material removal on ferrous and non-ferrous metals as well as wood stock preparation.
