The ITP Straight Styli Type F with a ruby ball tip is a precision probing stylus engineered for metrology setups that rely on disc and star styli. Featuring an extended M5 thread and a rigid tungsten carbide stem, it delivers stable, repeatable contact across a range of dimensions.

• Thread and overall length: M5 thread with a 33.5 mm overall length to fit standard mounting configurations for discs and star styli.
• Tip material: Ruby ball tip for high hardness and wear resistance, ensuring consistent contact during measurements.
• Stem material: Tungsten carbide stem, providing exceptional rigidity and dimensional stability under load.
• Ball size range: Ruby ball diameters available from Ø1.35 mm to Ø5.0 mm, suitable for various probing needs.
• Compatibility: Designed to work with grooved and clamping discs used in star stylus assemblies (requires these components for star stylus configurations).
• Customization: Other dimensions can be requested via the configurator or by email to tailor the stylus to your setup.

The combination of a rigid tungsten carbide shaft and a high-quality ruby ball delivers precise, repeatable measurements even in demanding environments. The extended thread simplifies mounting, enabling quick, secure integration with disc and star styli. With options for multiple ruby ball diameters, you can fine-tune contact geometry for your specific metrology tasks, from tactile probing to profile measurements. If you need dimensions beyond the standard 33.5 mm length or M5 threading, you can request custom specifications to fit your equipment and workflow.
