HARFINGTON Cup Grinding Wheel 4 Inch 120 Grits Silicon Carbide Cup Abrasive Wheel Green Aluminum Oxide for Knife Sharpening Machine Abrasive Tool - hta230331hh0793

• Size - Granularity: 120 Grits, Outer Diameter: 100 / 4-inch, Inner Diameter: 20mm / 0.79-inch, Height: 50mm / 2-inch Material - The cup grinding wheel is made of green silicon carbide, which has the characteristics of wear-resisting, high hardness, strong cutting ability, uniform particle size, high temperature resistance and strength. Feature - Cup sand wheel has good shape retention, can control the cutting precision, improve the workpiece surface quality. Good grinding performance, shorten the workpiece processing time and reduce the wheel replacement frequency, prolong the grinding wheel service life. Application - Green silicon carbide is suitable for the grinding of carbide, metal work piece and non-ferrous metal and non-metallic materials.Suitable for bench grinder and vertical grinder. Notice - The grit is smaller, the particle is coarse, and the grinding speed is faster. The grit is larger, the particle finer, and the smoother grinding surface is. The number of grit can be selected according to the need.
