An end mill is a cutting tool used in milling machines to shape and carve materials like metal, wood, or plastic. Unlike a drill bit, which primarily creates holes, an end mill can cut in multiple directions, allowing for more complex shapes and designs. It has a cylindrical body with sharp edges, or flutes, that help remove material as it spins. These tools come in various sizes and shapes, making them versatile for different tasks. They are often made from materials like high-speed steel or carbide, which provide durability and precision. Using an end mill can significantly enhance the efficiency of machining processes in industries such as manufacturing and engineering.
