• Abrasive material: zirconia alumina, which, due to its structure, continuously exposes new cutting surfaces during machining, creating a self-sharpening effect. Its high toughness makes it excellent for processing precious metals
• Reinforced fiberglass backing disc with a resin bond
• Designed for working with special metals, primarily stainless steel, high-temperature steel, heat- and corrosion-resistant steel, and stainless steel castings using angle grinders
