Norton Abrasives non woven high strength abrasive discs without holes are used for surface blending with consistency on ferrous alloys, woods & high tensile metals, thereby providing high resistance to tearing on sharp edges & burrs. They feature aluminium oxide grain construction for consistent performance and strong, smear-proof resin binders to produce light satin finishes. These discs can be ganged together to be used as wheels and are equipped with firm, flexible webs for durability when used on sharp edges & burrs, as well as intricate shapes & contours without changing the dimensions of the workpieces. Choose from a broad range of these discs, available in speed rates of 3000 and 4000 rpm.
