Flat end mills, also known as square end mills, are used for producing flat surfaces, slots, and sharp corners. They are a fundamental tool in CNC machining and are suitable for a wide range of materials. Flat end mills are commonly selected for general milling tasks where dimensional accuracy and versatility are required. B2B customers typically evaluate flat end mills based on material compatibility, flute count, tool length, and coating. These tools are often used in both roughing and finishing operations, depending on geometry and cutting parameters.
