Miniature end mills have small diameters, and they provide more precision and better control over material removal than end mills with larger diameters. They are rotated against a piece of stock to remove material in detailed milling applications such as dental milling or small-electronics manufacturing. Each end mill has flutes on its cutting head that carry chips away from the workpiece to prevent damage to the end mill or workpiece. Miniature end mills are used on CNC or manual milling machines.
