With a carbon-fiber stem, this stylus minimizes mass while maximizing stiffness, reducing deflection during probing and enhancing measurement stability. The ruby ball end provides a hard, wear-resistant contact surface that maintains accuracy across repeated passes. The generous 205 mm length enables access to recessed features, pockets, and deep cavities without sacrificing precision, making it ideal for complex assemblies and intricate geometries. The M3 thread ensures compatibility with a wide range of probe heads and accessories. If your application requires a different reach or ball diameter, additional dimensions can be configured or requested via email, giving you a tailor-made solution for your metrology workflow.
