Specification: Diameter 4, Thickness 3/5, Aperture 5/8, Maximum speed 15300RPM, Abrasive grain size - black silicon carbide 46.. : Uses high-strength wear-resistant fiber mesh as the base material, combines resin elastomer and high-quality diamond with a special process to form a high-strength, high wear-resistant grinding wheel.. Black Diamond Cup Wheel: The black diamond material is a high-strength, high-wearing honeycomb soft abrasive tool formed by combining high-strength wear-resistant fiber mesh as substrate and organically combining resin elastomer and corundum with a special process.. Excellent Performance: It does not damage the surface of the object, has uniform grinding force, uniform processing effect, wear resistance, strong water resistance, strong plasticity, and good softness. Dirt will not block the grinding surface, less peeling, low grinding sound and less dust.. Wide Application: The strip disc can be used to polish steel, plastic, new fiber products, and stone. Surfaces such as concrete. Used for pneumatic tools. Polishing and processing of complex surfaces and deep holes of various metals or non-metals, especially suitable for uneven surface and side grinding..
