3M Cloth Belt 302D is an aluminum oxide belt with open coat construction and a flexible J-weight backing that conforms well for sanding contours and complex parts. It is best-suited for light grinding, finishing, deburring and setting the grain on carbon steel and stainless steel, as well as soft metals like aluminum, brass, bronze and copper.

The 3M Microfinishing Film Roll 362L quickly cuts, shapes and polishes, delivering close-tolerance finishes for precision tooling and machining applications. Available in 9-100 micron grades, aluminum oxide is electrostatically oriented and bonded to a polyester film backing. A Type S (smooth) backsize coating provides slip resistance for microfinishing machines.

3M Trizact CF Cloth Belt 347FC features a unique formulation and “bricks and channels” abrasive design well suited for hard chrome grinding and finishing. The 347FC belt delivers consistent grinding performance without loading and dulling and the flexible X-weight cloth backing withstands high pressure grinding on hard metals.

3M Microfinishing Film Roll 373L quickly cuts, shapes and polishes, delivering uniform, close-tolerance finishes on parts used in metalworking applications.

The 3M Microfinishing Film Roll 272L produces close-tolerance surface finishes on a range of substrates – from gelcoat and soft rubber to fiberglass and metals. Designed especially for microfinishing applications of automotive powertrain components.

When traditional aluminum oxide belts aren’t cutting it, try 3M Cloth Belt 577F with alumina zirconia abrasive grain. It offers increased cutting efficiency compared to aluminum oxide, and has a heavy, water-resistant polyester backing that stands up to high-pressure applications and edge work.

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.

3M Trizact Cloth Belt 307EA uses proprietary microreplication technology where micron-graded aluminum oxide particles are formed into tiny pyramids of abrasive mineral and then coated on a rayon backing. As these pyramids wear, fresh, sharp mineral is continually exposed to produce a consistent cut and a predictable, fine finish.

3M Trizact Cloth Belt 217EA uses proprietary microreplication technology in which micron-graded aluminum oxide particles are formed into tiny pyramids of abrasive mineral and then coated on a JE-weight rayon backing. As these pyramids wear, fresh, sharp mineral is continually exposed to produce a consistent cut and a predictable, fine finish.

Take advantage of increased durability and cutting efficiency with 3M Cloth Belt 777F. This belt features a blend of 3M Ceramic Abrasive Grain and aluminum oxide that outperforms aluminum oxide belts in stock removal and metal finishing applications. The heavyweight cloth backing supports high-pressure applications, performs well on heat-sensitive metals, and can be used dry or with lubricant.
