Inspection Balls
Tooling balls and inspection balls (also known as reference balls / datum spheres) are high‑precision ground metal components with shoulder‑mounted stems. They serve as fixed physical coordinate origins for inspection, machining and assembly workflows. Though small in size, their sphericity, shoulder perpendicularity and surface finish directly define the reliability of your entire measurement chain.
