Powered by a 250W induction motor and fully guarded for operator safety, this dual-purpose grinder is specifically designed for sharpening fine blades and cutting tools. This model features a 200mm wet grinding stone running at 130rpm for gentle, cool sharpening that prevents damage to tempered edges, alongside a 150mm dry stone operating at 2850rpm for faster material removal.
