CBN Grinding Wheel, 8 Inch Dia x 1 Inch Wide x 5/8 Inch Bore for Sharpening Woodturning Tools,Bench CBN Grinding Wheel, 8 Inch Dia x 1 Inch Wide x 5/8 Inch Bore for Sharpening Woodturning Tools,Bench Suitable Size: 8 inches in diameter, 1 inch wide, Bore 5/8 inches, 180 grit.stainless steel body, more smoothly, does not rust, high hardness, high compressive strength, good wear resistance and long service life. High performance: Electroplated diamond flat grinding wheels are mainly used for grinding and cylindrical grinding of hard alloy measuring tools, tungsten steel, high-speed steel, alloy steel, glass, gemstones, jade, jadeite, honey wax raw , magnetic materials, ceramics, molds, etc. New upgrade: Compared with the traditional diamond grinding wheel, the CBN grinding wheel generates less heat, and is more suitable for hard alloy, high alumina porcelain, optical glass, gem, semiconductor materials, stone materials, etc. More professional: Use this wheel for the most precise grinding even on the most common grinders. 1000 RPM to 3600 RPM is recommended. As a high-performance abrasive, CBN has high compressive strength, generates less heat and good abrasive shape retention long service life. perfect Compatibility: Meticulously manufactured for a precise fit, eliminating the need for "Truing" or "Dressing" adjustments. These wheels optimize the performance of budget-friendly grinders, rivaling industrial . The Aluminum arbor reducing bushing offers superior smoothness compared to plastic alternatives. CBN grinding wheels are perfect for high-speed steel product grinding.
