Ball nose router bits are designed with a rounded tip, perfect for creating smooth, contoured cuts in both 2D and 3D applications. These bits are ideal for carving intricate details, shaping curves, and creating rounded edges in wood, plastic, and other soft materials. They are commonly used in CNC machines for tasks such as 3D sculpting, engraving, and producing smooth finishes on curved surfaces. The ball nose design helps minimize splintering and allows for a clean, precise cut, making it a popular choice for detailed and complex projects.
