A milling cutter is a specialized tool used in the process of milling, which involves removing material from a workpiece to shape it into a desired form. These cutters come in various shapes and sizes, allowing them to perform different types of cuts, such as flat, curved, or angled surfaces. They are typically made from high-speed steel or carbide, providing durability and precision during operation. Milling cutters are mounted on a milling machine, which rotates the cutter against the workpiece. This process can create intricate designs and features, making milling cutters essential in industries like manufacturing and metalworking. Common types include end mills, face mills, and slab mills, each designed for specific applications.
