Choosing High vs. Low Densities Our Standard Abrasives™ Light Deburring Wheel utilizes a fine grade silicon carbide mineral. These wheels vary in density, ranging from 6 to 8. Higher density wheels tend to be more durable and have a longer service life. Lower density wheels indicate softer feel. This lower density enables the wheel to be more flexible and conform to the substrate. Light deburring wheels tend to be less aggressive and finish finer than other convolute wheels. Smear-Resistant for A Brighter Finish These wheels are convolute wheels, meaning they must be run in one direction as indicated by the arrow on the side of the wheel. The abrasive web, made with resin and silicon carbide mineral, is wound around the wheel's core. The silicon carbide mineral is bonded with a smear-resistant resin that will not smudge or stain the substrate. These attributes contribute to a cleaner, brighter finish on the substrate. Our Light Deburring Wheel is a great starting point for your light blending, polishing, and deburring applications. Consider it a trusted tool for achieving a fine finish on the workpiece.
