Flexible Performance
Hardworking and reliable, our 3M Cloth Belt 211K works well for blending and repairing metal finishes, as well as fine sanding and polishing applications. The closed-coat aluminum oxide yields an aggressive cut and a fine finish. Used for polishing crankshafts, it’s also exceedingly flexible relative to stiffer cloth-backed abrasives.
Tough, Durable Aluminum Oxide
Aluminum oxide (AO) mineral delivers a soft scratch pattern that is often desirable for finishing and polishing. AO is the abrasive of choice among industrial professionals because of its fast cut and long life. It’s suitable for use on many metals, including mild steel.
Abrasive belts come in many different widths and lengths and are used on a variety of different belt sanding tools for many different applications on metal. At 3M we offer a broad selection of belts to fit most any industrial belt sander.
