Drill Bits, End MillsDrill bits and end mills are cutting tools that are used in a variety of manufacturing and fabrication processes. Drill bits are tools that are used to create holes in a variety of materials, while end mills are tools that are used to mill, or remove material, from the surface of a workpiece. Both types of tools are commonly used in applications such as drilling, milling, and other machining operations. Drill bits are available in a wide range of sizes and styles, and can be used to drill holes in materials such as wood, metal, and plastic. End mills are also available in a variety of sizes and styles, and can be used to mill a variety of materials, including metals, plastics, and composites.
