The combination of a high-rigidity carbide stem and precisely formed ruby balls provides stable, repeatable probing across a range of features and materials. The small ruby contact point minimizes surface wear on delicate workpieces while maintaining accurate touchpoints during repeated measurements. With a compact 18.3 mm length and M2 threading, this stylus integrates smoothly into standard measurement setups. For applications requiring non-standard dimensions or ball diameters, additional sizes can be requested through the configurator or by e-mail to ensure the right geometry for your micro-features and recessed areas.
