4″ x 6mm Green Fiber Grinding Disc Cutting Disc, Licon.

The colors of fiber grinding discs—black, green, and red—typically indicate the type of abrasive material and their intended applications.
Green grinding discs are usually made of silicon carbide, primarily used for grinding non-ferrous materials (e.g., aluminum, brass, and copper) and softer materials like stone, glass, and ceramics. Green discs are sharper and harder but wear faster when used on metals. Designed for general-purpose grinding on ferrous metals (e.g., mild steel, iron) and sometimes wood or plastics.

These colors and their meanings can vary slightly by manufacturer, so checking the product specifications for the intended use is always a good practice.
