Which type of milling cutter is designed to machine large surfaces and can be mounted on an arbor?

The shell mill is the type of milling cutter designed specifically to machine large surfaces and can be mounted on an arbor. This cutter consists of a thin cylindrical body with cutting edges on its outer circumference and sometimes on the face as well. The arbor mounting allows for stability and effective transfer of torque during milling operations, making it ideal for heavy-duty machining of flat surfaces, grooves, or complex contours.

The design of the shell mill permits the use of multiple cutting inserts or teeth that can be replaced as they wear, providing advantages in terms of tool life and cost-effectiveness. Its ability to cover a wide surface area efficiently makes it a versatile tool in machining operations involving large components.

The other types of cutters mentioned, such as the side mill, circular cutter, and face cutter, have their specific applications but do not share the same profile or mounting capabilities as the shell mill, which is particularly suited for extensive surface machining tasks.
