Product Description
The Norton abrasive disc combines load-resistant stearate coating, flexible backing, and P-graded ceramic aluminum oxide to give 3X the performance of standard paper discs. This disc is used for preparing primed and painted surfaces, sanding plastics and fiberglass, and bare wood sanding on composites, marine gel coat, furniture, and nonferrous metals.
Coated abrasives have individual abrasive grains spaced at a predetermined distance from one another. This is a closed-coat disc. A closed coat covers 100 percent of the surface with abrasive grains, for more stiffness and better surface finish than an equivalent open coat, where abrasive grit covers 50 to 70 percent of the surface. The paper backing is flexible, and offers a more consistent finish than a cloth or fiber backing, while being thicker and more durable than a polyester film backing. This disc is suitable for use with a die grinder or orbital sander. NorGrip hook and loop fastener is easy to press on and tear off, and helps make disc changes fast. Use with molded rubber back-up pads on a grinder, using a hard pad for aggressive cutting, a medium pad for general purpose applications, or a soft pad for contours and fine finishing work. Or, with a random orbital sander, use a foam back-up pad to match the application. Foam pads come in different combinations of shape and density for finer or more aggressive work. For example, use a low profile for uniform contact with the work surface, a tapered edge for small contours or inside corners, soft density for 320 grit and finer sanding, and medium density for grits coarser than 320.
