【Suitable Size】Engineered with an 8-inch diameter and 5/8-inch bore for universal bench grinder compatibility. As a high-performance abrasive, CBN grinding wheel 8-inch has high compressive strength, generates less heat and good abrasive shape retention long service life 【Industrial-Grade Durability】Forged with corrosion-resistant stainless steel core and permanent CBN grain bonding technology. The 8 CBN grinding wheel withstands 3600 RPM operations without deformation, offering lifespan than conventional wheels 【Professional-Grade Edge Refinement】Optimized CBN wheel 8-inch geometry delivers razor-sharp edges on HSS tools, woodturning chisels, and planer blades. Maintains cutting efficiency through 1000+ sharpening cycles without requiring dressings 【Universal Speed Compatibility】Synchronizes seamlessly with 1000-3600 RPM grinders, outperforming standard wheels at both low and high velocities. The CBN grinding wheel's for the most precise grinding even on the most common grinde 【Maintenance-Free Operation】Precision-calibrated CBN wheel 8-inch requires no truing/dressing adjustments throughout its service life. Self-sharpening abrasive structure maintains optimal profile for gouges, scrapers, and lathe tools. Suitable Size: 8 inches in diameter, 1 inch wide, Bore 5/8 inches, 180 grit. As a high-performance abrasive, CBN has high compressive strength, generates less heat and good abrasive shape retention long service life. High Quality: Stainless steel body, more smoothly, does not rust, high hardness, high compressive strength, good wear resistance, and long service life. This kind of CBN wheels can be used in many sharpening works. Excellent Performance:This CBN wheel is plated with the best quality CBN grains. It is the best choice for grinding turning tools, chisels, planer knives, wood turning tools, high speed steel cutting tools and so on. Applicable to most bench grinders: This wheel is for the most precise grinding even on the most common grinders. 1000 RPM to 3600 RPM is recommended. Ideal 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 counterparts.
