What Is a Face Milling Cutter Arbor?

A face milling cutter arbor is the adapter that mounts a face mill insert cutter to the spindle of a milling machine. The arbor transfers rotational torque from the spindle to the cutter while maintaining precise concentricity, which is critical for achieving flat, smooth surfaces. Choosing the right arbor for your cutter diameter ensures optimal cutting performance and extended tool life.

For guidance on safe machining practices and tool safety, refer to the OSHA Milling Machine Safety Guidelines.
