See the Norton RazorStar® R990S 36+ grinding belt in action!


Watch as Norton RazorStar® R990S 36+ gets to work in a manual operation, on carbon steel, inox and inconel. Compared to a conventional ceramic grain belt, we saw a cut rate that was twice as fast, the belt lasted longer, cut cooler and increased efficiency, performance and quality when used on all three metals, all thanks to the exceptional sharpness of the engineered shaped ceramic grain.
