Arbor
In the context of hardware, an arbor is a cylindrical metal shaft or spindle that is typically used in conjunction with various tools and equipment. It often serves as a central axis onto which other components, such as blades, grinding wheels, or drill bits, can be attached. Arbors are commonly found in tools like saws, grinders, and drills, facilitating the secure mounting and rotation of cutting or abrasive elements. They play a crucial role in providing stability and precision during the operation of such tools, ensuring efficient and controlled performance.
