Milling tools are specialized instruments used in the machining process to remove material from a workpiece. They operate by rotating against the material, allowing for precise shaping and cutting. Common types of milling tools include end mills, face mills, and slot drills, each designed for specific tasks and materials. These tools are typically made from high-speed steel or carbide, providing durability and efficiency. They are essential in various industries, including manufacturing, automotive, and aerospace, where precision and accuracy are crucial for producing components and parts.
