Merit’s ALO Resin Bond quick-change abrasive discs are engineered specifically for light-to-medium grinding, blending, and finishing on contours and flat surfaces. ALO Resin Bond discs are suitable for general-purpose deburring and blending where greater edge durability is required. ALO Plus discs feature a grinding aid for cooler temperature grinding on exotic alloys.

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. All Merit PowerLock Discs feature laminated construction which provides a tough, durable backing, reducing snagging and shredding. 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 features a resin bond. Resin bonds have good moisture resistance, are harder and less flexible than glue bonds, and have good heat resistance and grain retention. Resin bonds are useful for abrasive operations with high operating speeds, impact, and sudden loading, as the resin bond is strong. The PowerLock quick-change system allows for easy disc mounting and removal to increase productivity by reducing the time required to change discs. 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.

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.

Merit Abrasives has been manufacturing abrasives for the deburring and finishing industries since 1945, and pride themselves on their quality and focus on service. Saint-Gobain owns Merit, and has been recognized as a Global 100 Sustainable Company. Saint-Gobain has also earned ISO 9000 and 14001 certification for quality and environmental management standards.
