A face mill is a type of cutting tool used in machining to create flat surfaces on a workpiece. It consists of a rotating cutter with multiple teeth that remove material as it moves across the surface. Face mills are commonly used in milling machines and are effective for producing smooth, even finishes. These tools can vary in size and design, allowing for different cutting depths and widths. They are often made from high-speed steel or carbide, which provides durability and resistance to wear. Face mills are essential in industries like manufacturing and metalworking, where precision is crucial.
