This stylus delivers a reliable touch in coordinate measuring and inspection workflows. The carbide stem minimizes deflection under probing forces, helping you achieve consistent results across multiple measurements. The ruby ball tip provides a hard, smooth contact surface that reduces wear and preserves accuracy over time. With its generous 82.5 mm length and secure M5 connection, it’s well-suited for accessing tight pockets, dense fixtures, and a variety of measurement setups. If you need a different ruby-ball diameter for specific parts or tolerance requirements, additional sizes are available on request through the configurator or by email.
