Description

HNHOVERSTOCK
Merit Shurstik PSA Disc, Paper Backing, Adhesive Backed, Aluminum Oxide, 1/2 inches Diameter, 120 Grit (Pack of 100)
Aluminum oxide is durable and the most common abrasive grain
Resin bond for heat and moisture resistance, and retaining abrasive grains well
Closed coat for a higher-quality finish than an open-coat disc
Pressure-sensitive adhesive sticks without messing with solvents, water, or heat
Suitable for high-speed grinding and polishing
Merit Shurstik high-speed PSA discs are suitable for high-speed grinding and polishing on a variety of materials, while making it simple to change discs, by peeling and sticking the disc to its backing pad.
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. 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. Pressure-sensitive adhesive sticks when pressure is applied, without messing with solvents, water, or heat. 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.
