The ITP Straight Styli Type B with a ruby ball is a precision, M5-threaded stylus designed for metrology professionals who need reliable, repeatable contact in tight measurement spaces. Built for everyday standard use, it pairs a robust tungsten carbide stem with versatile ball options to fit a range of probing tasks.

• Material and rigidity: Extremely rigid tungsten carbide stem delivers consistent measurements and long-term durability.
• Stem configuration: Designed for either single-point or multi-stepped configurations to suit different probing strategies.
• Ruby ball range: High-quality ruby balls from Ø0,2 mm to Ø1,5 mm provide precise, smooth contact with tiny radii.
• Thread compatibility: M5 thread enables secure mounting to compatible probes and fixtures for quick swaps.
• Overall length: 30 mm overall length offers compact compatibility with standard measuring setups.
• Size customization: Other ball sizes and configurations can be requested via the configurator or by e-mail.

In practical use, this stylus delivers dependable contact for routine inspections, calibration, and micro-scale gauging. The tungsten carbide stem minimizes wear and maintains measurement accuracy over time, while the ruby ball's hardened surface reduces wear on test artifacts and produces repeatable touch points. The option to choose ball diameters and stem configurations lets you tailor the touch to feature size and material, minimizing measurement risk and downtime. If you have a specific size requirement, you can request it through the configurator or by email to match your exact application.
