A ball end mill is a type of cutting tool used in milling machines. It features a rounded end, which allows it to create curved surfaces and intricate shapes in materials like metal, wood, and plastic. This design makes it ideal for tasks such as contouring and machining complex geometries. These tools are commonly used in various industries, including manufacturing and woodworking. The rounded tip of a ball end mill enables smooth finishes and precise cuts, making it a popular choice for creating molds, dies, and other detailed components. Proper selection and use can enhance the efficiency of machining processes.
