Norton Metalite R228 Speed-Lok TR quick-change discs allow for easy disc mounting and removal to increase productivity by reducing the time required to change discs. These durable cotton-backed discs are suitable for light to medium pressure grinding, blending, leveling, and finishing applications.
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 cloth backing is stiffer, tougher, and thicker than a paper or film backing. Cloth resists tearing while bending and flexing during use. This disc is suitable for use with a die grinder. Use with molded-rubber backing pads. Use a hard pad for aggressive cutting, a medium pad for general-purpose applications, or a soft pad for contours and fine finishing work.
Aluminum oxide is a widely used and versatile abrasive material. It is a tough, fracture- and wear-resistant grit that works well with a broad range of materials, from metals to wood. Aluminum oxide is more durable than silicon carbide and often used for material removal and finishing.
Abrasives are used for a variety of applications from shaping a part to fine finishing, depending on the grit size. Low grit numbers like 40 are coarse and are used for removing excess material and shaping a part. High grit numbers like 400 are fine and help to create a smooth surface finish.
