The 400-grit satin disc is designed for sanding, satin-finishing, removal of deposits, flash rust and paint. The disc leaves a matte effect and prepares the surface for the main polishing. It is made of 4 layers of flexible nonwoven fabric that conforms in shape to the polished surface. Perfect for large surfaces.

The discs have a 14mm diameter hole to fit polishing machines, electric grinders and air-polishers with M14 threads. The discs are ventilated, reducing the risk of overheating the polished surface and allowing longer operation with stronger pressure.
