Description Higher Cut Rate A breakthrough innovation of razor-sharp ceramic grain, with a tough microstructure, cuts faster and removes more material. This is combined with the highest percentage of grains applied to the backing in an upright position for razor-sharp cutting. Longer Life Unique patented geometry enables the grain to stay sharp as new razor-sharp edges are exposed as the grain fractures. The innovative design of Norton RazorStar? promotes improved grain retention, providing unparalleled belt life. Cooler Cut The unique sharp design of the grains, combined with the belt?s special topsize grinding aid, helps to significantly reduce heat generation ? resulting in less thermal damage to the workpiece. Upright Grain – Primed to Cut Norton RazorStar? belts fully leverage the sharpness of the engineered shaped grain. Grains that lie flat do not cut, so thanks to a new patent-pending method designed to position grains upright on the backing, belts deliver the sharpest grinding possible compared to competitor belts. What?s more, the high number of grains per unit area, topsize coating and heavy weight backing are designed to promote grain retention and self-sharpening fracturing, to maintain powerful grinding performance over prolonged periods in medium to high pressure applications.
