Merit Micro Mini Grind-O-Flex Abrasive Flap Wheel, Round Shank, Aluminum Oxide, 3/4" Dia., 5/8" Face Width, Grit 180, 35000 Max RPM (Pack of 10)

Merit micro mini Grind-O-Flex flap wheels are useful for polishing and light deburring of internal diameters, such as holes and grooves, that may be as small as 1/2”.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. 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. 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.

• Aluminum oxide is durable and the most common abrasive grain
• Cloth backing is stiffer, tougher, and thicker than a paper or film backing
• Flap wheels conform better to the workpiece than a disc, and are commonly used for grinding and finishing on irregularly shaped workpieces
• Round shank for use on a wide variety of toolholding systems
• Micro mini flap wheels are mounted on 1/8” diameter steel shank for use with many toolholding systems
