SPECIFICATIONS: 8" diameter x 1" width, 80 grit CBN grinding wheel with 5/8" arbor; built on 6061 aluminum core with full nickel plating for strong durability and corrosion resistance, perfect for bench grinder use. PRODUCT STRENGTHS: CBN abrasive offers consistent cutting performance, high edge precision and longer service life, outlasting traditional abrasives. Nickel-plated structure ensures great shape retention and resists deformation during extended use. GRINDING EFFICIENCY: Improves efficiency for HSS sharpening and tool shaping with less downtime. Requires no truing or frequent adjustments, lowering maintenance while ensuring smooth, high-efficiency grinding. WIDE COMPATIBILITY: Fits most standard 8-inch bench grinders, with ideal operating speed of 1000–3600 RPM. Well-balanced to reduce wobble and vibration for stable, accurate grinding and polishing. APPLICATION SCENARIOS: Suitable for woodturning tools, chisels, planer blades, HSS, carbon steel and hardened steel. Grinds with low heat to avoid thermal damage, minimizes material removal and extends tool life. Why choose CBN grinding wheel:CBN grinding wheels have been used in manufacturing processes for many years and are now available for common bench grinders. CBN crystals are electroplated on to a precision aluminum grinding wheel substrate resulting in the finest grinding wheels available today. CBN wheels outperform common stone wheels in many ways. Features:Wheels are made from an aluminum core, which is lighter in weight than steel and will run smoother on all grindersIdeal for sharpening woodturning tools (High Speed Steel only)Designed for use with bench type grinders; 1000 RPM (Preferred) or 3600 RPMWheel diameter does not change over time.What's in the box:1 x CBN Grinding Wheel 8 inch 80 grit1 x A pair of anti cutting gloves.
