Setting the new standard in grinding productivity, efficiency, and quality, Norton RazorStar belts are designed for the toughest robotic and off-hand applications. Reach for the star for less machine time, reduced energy consumption, and ultimately, more parts per belt. Breaking Down The Grain Norton RazorStar belts utilize an engineered ceramic shaped grain. The grain’s unique shape allows for a sharp initial cut while fracturing in a precise manner during use to create new sharp cutting points for higher and faster stock removal rates. The grains stay sharp for longer, reducing dulling, and allowing for cooler cutting, longer belt life and fewer belt change overs.
