Ball nose bits. Sometime they are also called round nose bits, and they have many types according to the shapes of such CNC engraving bits. The cutting edge of ball nose CNC end mills is in arc shape, which could form a hemisphere during engraving process. So the ball nose bits are subject to uniform force when cutting and can cut smoothly.
