Designed to minimize deflection and maximize measurement consistency, the carbide stem maintains stiffness during contact, helping you capture accurate footprints on small or delicate features. The ruby ball tip provides a durable, low-wear contact point that supports repeatable readings over many cycles. With a universal M3 thread and a 22 mm length, this stylus integrates smoothly into common probing systems and workflows. If your application requires a different tip diameter or stepped configuration, you can request a custom size through the configurator or by emailing the supplier.
