3M™ Cloth Belt 777F delivers strong durability and fast cutting for high-pressure grinding and finishing jobs. Made with a blend of ceramic and aluminum oxide grains, this belt removes more material and lasts longer than standard aluminum oxide belts. Its sturdy cloth backing supports dry or wet use, making it ideal for tough applications on metal, especially heat-sensitive alloys like stainless steel.

The grinding aid helps control heat during use, which protects delicate materials from damage. A resin bond secures the abrasive, ensuring strength during heavy use. Whether you’re deburring, shaping, or finishing, this belt gives you steady results across various surfaces and machines.
