Flute type significantly impacts chip evacuation and cut quality. For plastics, spiral “O” single flute bits are often best because they produce smooth cuts, minimize melting, and efficiently remove chips. Some applications benefit from ball nose or compression flutes for 2D/3D carving or double-sided materials. The 51404-K and 51411-K both feature spiral “O” flutes for clean plastic cutting, while the 46280-K offers a ball nose for detailed 3D work. Multiple flute types are available to best match your cnc bits for plastic application.
