With a carbide stem for exceptional rigidity, this straight stylus minimizes deflection during probing, delivering consistent contact and repeatable results across repeated measurement cycles. The Al2O3 ceramic ball provides wear resistance and stable contact geometry, helping maintain accuracy over time. A long reach of 200 mm overall length (175 mm measuring length) makes it ideal for accessing recessed features or large components without sacrificing precision. The M5 threading ensures compatibility with standard probe heads and accessories used in CMM setups and inspection stations. If you need a different ball size or length, additional options are available by configuration or through email to tailor the stylus to your exact workflow.
