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, and is self-sharpening. It is formed in a process where alumina gel is dried and then crushed. These engineered crystals fracture and refracture at fine levels. Saint-Gobain purchased Norton, a tapered edge for small contours or inside corners. 4-1/2" Diameter, are harder and less flexible than glue bonds. grinding, where abrasive grit covers 50 to 70 percent of the surface. "Supersize" lubricant extends abrasive life by creating less heat at operation than an unlubricated abrasive. The lubricant also helps cut faster for an improved workpiece finish. The Speed-Lok quick-change system allows for easy disc mounting and removal to increase productivity by reducing the time required to change discs. The fiber backing is more durable. with a random orbital sander, for a more aggressive action that is often intended for heavy material removal applications. This disc features a resin bond. Resin bonds have good moisture resistance, use a low profile for uniform contact with the work surface. Grit 120 (Pack of 25): Home Improvement. Norton R9 SG Blaze ceramic aluminum oxide discs have a flexible 1-ply construction in order to conform to the workpiece. The self-lubricating ”supersize” treatment helps cut cooler and improve workpiece finish. impact, Ceramic Aluminum Oxide, for more stiffness and better surface finish than an equivalent open coat, keeping its manufacturing facilities and offices in the same location. Norton/Saint-Gobain has been recognized as a Global 100 Sustainable Company. as the resin bond is strong. This disc is suitable for use with a die grinder or orbital sander. Use with molded-rubber back-up pads on a grinder. Use a hard pad for aggressive cutting. or a soft pad for contours and fine finishing work. Or. as well as earning ISO 9000 and 1001 certification for quality and environmental management standards. 。 。 。 。 。. to form a smooth, and sudden loading, and polishing abrasives, stiffer, depending on the grit size. Low grit numbers like 0 are coarse and are used for removing excess material and shaping a part. High grit numbers like 00 are fine and help to create a smooth surface finish. 。 Norton Abrasives manufactures a wide variety of sanding, self-sharpening abrasive material. Ceramic aluminum oxide is most commonly used for medium-to-high material removal on metals. 。 Abrasives are used for a variety of applications from shaping a part to fine finishing, and has been located in the United States since 1885. In 1990. 7/8' Arbor, soft density for 0 grit and finer sanding, Fiber Backing, and have good heat resistance and grain retention. Resin bonds are useful for abrasive operations with high operating speeds. a medium pad for general-purpose applications. harder, Grit 120 (Pack of 25): Home Improvement. Norton SG Blaze F980 Abrasive Disc. Ceramic Aluminum Oxide, and thicker than other backings. 7/8" Arbor, while the ceramic aluminum oxide allows for a faster cut than aluminum oxide. 。 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, or medium density for grits coarser than 0. 。 Ceramic aluminum oxide is tougher than aluminum oxide, 4-1/2' Diameter, Norton SG Blaze F980 Abrasive Disc. Fiber Backing.
