🔍 Yes, but you should choose the right type of spiral bit. For soft metals like aluminum and for acrylic or other plastics, an **""O-flute"" spiral bit** (single flute up-cut design) is recommended. SpeTool offers O-flute bits that are specifically designed for these materials, providing a smooth cut and good chip evacuation to avoid melting plastic or clogging with metal chips. For example, a SpeTool O-flute upcut bit works well on aluminum and acrylic:contentReference[oaicite:10]{index=10}. Always use proper feed speeds and coolant/air if needed when cutting metal.
