CNC Milling: Introduction to cutting tools | wikimal
A ball nose end mill, also known as a spherical end mill or ball end mill, has a semisphere at the tool end. Ball nose end mills are used on workpieces with complex surfaces. Choosing flat end mill vs. a ball end mill will determine the characteristics of the tooling marks (or lack thereof) on your model.
