Sanding With Wide and Narrow Belts

The choice of sanding grain material, for example, is critical, but other factors such as adjustment of sanding unit, sanding speed selection, and handling are also essential. When you choose a belt from Mirka, you can be confident that you will get the most efficient sanding results without compromising the quality.
