Suitable Size: 6 inches in diameter, 1 inch wide, bore 1/2 inch, 600 grit. Stainless steel body, smooth surface, rust-resistant, high hardness, high compressive strength, good wear resistance, and long service life. High Performance: Electroplated diamond flat grinding wheels are used for grinding and cylindrical grinding of hard alloy measuring tools, tungsten steel, high-speed steel, alloy steel, glass, gemstones, jade, agate, magnetic materials, ceramics, etc. New Upgrade: Compared with traditional diamond grinding wheels, CBN grinding wheels generate less heat and are suitable for hard alloy, high-alumina porcelain, optical glass, gemstones, semiconductor materials, and stone materials. More Professional: Designed for precise grinding on common bench grinders. Recommended operating speed: 1000 RPM to 3600 RPM. CBN offers high compressive strength, low heat generation, excellent abrasive shape retention, and long service life. Perfect Compatibility: Precision-manufactured for exact fit, eliminating the need for truing or dressing. Optimizes performance on budget-friendly grinders. Aluminum arbor reducing bushing provides superior smoothness compared to plastic alternatives. Suitable for high-speed steel product grinding.
