Arbor vs. Mandrel — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Updated on March 26, 2024
An arbor is a shaft or spindle for holding cutting tools or workpieces, mainly in woodworking or metalworking, while a mandrel is a tool used to shape, support, or hold workpieces in manufacturing processes, often for hollow or tubular shapes.

Key Differences
An arbor is primarily utilized in the context of machining, where it serves as a support structure or carrier for various tools or pieces being worked on. It's essential in operations like milling, where stability and precision are paramount. Arbors are designed to fit into a machine's spindle, allowing the attached tools or workpieces to be manipulated with high accuracy. On the other hand, a mandrel, also known as a mandril, is specifically designed to support the internal structure of hollow objects during processes like bending, shaping, or machining. Mandrels ensure that such objects retain their desired shape and structural integrity by preventing collapse or deformation.
Arbors can be found in a wide range of applications from the simple holding of saw blades to the complex setup in CNC (Computer Numerical Control) machining centers. They are versatile components that facilitate the secure attachment and precise operation of cutting tools. Meanwhile, mandrels are often tailored for specific tasks, such as in tube bending operations where they support the interior of the tube to achieve smooth, tight bends without wrinkling the material.
The distinction between an arbor and a mandrel can sometimes blur, especially since both serve as critical support mechanisms in machining and manufacturing. However, their primary differentiation lies in their application focus. Arbors are more about mounting and rotational support for tools or workpieces, whereas mandrels are about internal support for shaping or processing materials, particularly hollow sections or tubes.
In practical terms, the selection between an arbor and a mandrel is determined by the nature of the manufacturing process. For operations requiring external support, precision alignment, and rotation of a tool or workpiece, an arbor is the go-to choice. Conversely, for processes that necessitate internal support to maintain the shape or integrity of a workpiece, especially to prevent deformation during machining or bending, a mandrel is essential.
Both arbors and mandrels play crucial roles in manufacturing and machining industries, ensuring that products meet the necessary specifications with precision. Their use is fundamental in achieving the desired quality and functionality in various applications, from automotive manufacturing to custom furniture making.
