The best CNC bit for achieving a smooth finish is generally a carbide spiral upcut or downcut bit with a high flute count, such as a 2-flute or 3-flute. For the finest surface, consider using a straight or compression bit, particularly on wood, as they reduce tear-out effectively. Always make sure your bit is razor-sharp and choose the appropriate feed rate for your specific material to ensure optimal results. In my shop, I rely exclusively on AMANA Tools Bits for their reliability and performance, even during the most demanding jobs, guaranteeing consistent, high-quality finishes every time.
