- Thread: M3 XXT thread for secure attachment to compatible probe heads
- Overall length: 30 mm from tip to base, providing a compact, easy-to-handle profile
- Holder material: Ø5.0 mm titanium holder for lightweight strength and corrosion resistance
- Stem material: Carbide stem delivering extreme rigidity and minimal flex during probing
- Tip material: Ruby ball tip, with high-quality diameters available from Ø0.8 mm to Ø2.5 mm

The combination of a titanium holder, carbide stem, and ruby-ball tip delivers precise, repeatable contact with a variety of features. The titanium holder's Ø5.0 mm diameter enhances durability without adding unnecessary weight, while the carbide stem minimizes deflection under load, supporting accurate data across standard probing tasks. Ruby ball tips provide smooth contact with minimal wear, ensuring consistent performance as you scan small features or verify geometric tolerances. If you need a different ruby-ball size, you can request it through the configurator or by email, ensuring you have the right balance of contact area and resolution for your application.
