Feature:1. Abrasives are characterized by high hardness, high compressive strength and good wear resistance, making them an ideal grinding tool.2. The hardness of green silicon carbide is second only to boron carbide and diamond, it is brittle, has abrasive grains and has thermal conductivity.3. The grinding wheel has uniform abrasive grains, high grinding accuracy, good surface smoothness, low abrasive consumption and is durable.4. Suitable for grinding hard alloys, optical glass, ceramics, gemstones, agate, honing cylinder liners and other hard and brittle materials.5. Long service life thanks to hard silicon carbide, high material removal rate, deburring.Specification:Item Type: Grinding WheelMaterial: Green Silicon CarbideColor: GreenProduct Size: Approx. 75 x 32 x 20mm/2.9 x 1.2 x 0.7in (Diameter x Thickness x Aperture)Compatible: For grinding hard alloys, optical glass, ceramics, gemstones, agate, honing cylinder liners and other hard and brittle materials.Package List:1 x Grinding WheelNote:The grinding wheel installed or used every other day should be idle for more than one minute before use. Do not stand in front of the grinding wheel.
