Can I use an angle grinder to cut hot rolled aluminum coils?

Yes, you can use an angle grinder to cut hot rolled aluminum coils, but you must take precautions. Use a grinding disc specifically designed for metal cutting, preferably one with a diamond or carbide grit for better performance on aluminum. Ensure the grinder is equipped with a safety guard and wear appropriate safety gear, including goggles and gloves. Be aware that aluminum can be reactive when heated, so cutting may produce sparks and fumes; ensure proper ventilation. Always follow the manufacturer's guidelines for your specific angle grinder and safety regulations.
