• Premium aluminum oxide offers increased cut-rate and abrasive life
• Open coat construction provides improved cut on all woods and helps prevent loading
• Heavyweight cloth backing provides durability for high-production environments
• Washable backing enables repeated use on high-loading substrates such as pine
• Resin bond construction withstands high heat and pressure for longer service life

3M™ Cloth Belt 340D is an open coat premium grade aluminum oxide cloth belt that provides durability for aggressive stock removal, resists loading, and is suitable for a variety of applications on wood and metal. This belt is recommended for wide belt sanding, edge sanding, or portable belt sanding.

Fast-cutting aluminum oxide abrasive grains are resin-bonded to a durable cotton cloth backing to provide continuous cut and long-life. This open coat and load-resistant coating make this belt particularly favorable for sanding soft woods. Additionally, the washable backing is suitable for high production environments where the belt may need washing at intervals to remove soft wood resin or pitch buildup.

Aluminum oxide mineral is a popular choice among industrial professionals because of its cut-rate, durability, and long life. It can be used on a wide variety of materials in both woodworking and metalworking, including ferrous alloys, and is the most commonly used industrial abrasive. The abrasive particles are adhered to the cloth backing with resin, creating a strong bond that withstands high heat and pressure.

Belts come with a film media splice which achieves a secure bond with a joining film that minimizes chatter marks, ensures a smooth-running belt, and produces consistent finishing results
