Thanks to the carbide stem’s rigidity, this stylus minimizes flex and deflection during contact, delivering repeatable measurements across a wide range of dimensions. The silicon nitride ball is particularly effective for scanning untreated aluminium, helping to minimize wear and wear-induced measurement drift. With an M2 thread and a compact 42 mm length, it fits a broad array of inspection setups and handheld probing scenarios. If your measurement needs require different ball sizes, you can configure or request alternative diameters through the available configurator or via email.
