This stylus is crafted to minimize flex and maintain repeatable results in coordinate measuring machines, calibration rigs, and precision probes. The ruby ball provides a hard, wear-resistant contact point with smooth interaction on diverse materials, while the carbide stem preserves geometry under repeated use. If you need a non-standard ball size, you can request a custom diameter to fit your specific inspection workflow, helping reduce setup time and improve measurement consistency.
