Abrasive belts are flexible bands of abrasive material that are used to grind, sand, or polish surfaces. They are commonly made of coated abrasive material such as aluminum oxide or silicon carbide. Buffs, on the other hand, are tools that are used for polishing or shining surfaces. They are typically made of cotton or felt and are often used in conjunction with a polishing compound.

Abrasive belts are commonly used in the metalworking industry for tasks such as grinding, deburring, and sanding. They are also used in woodworking for shaping and sanding wood surfaces. Buffs are commonly used in the automotive industry for polishing car parts, and in the jewelry industry for polishing precious metals and gemstones.
