The ITP Straight Styli Type D with Ruby Ball is a precision probing stylus designed for metrology professionals who demand repeatable, tiny-scale contact measurements. Built for reliability in CMM and micro‑probing tasks, it combines a rigid tungsten carbide stem with precision ruby ball tips.

• Thread: M5 thread compatible with standard probe fixtures and accessory kits.
• Overall Length: 32 mm overall length (Model FHM500511032) to suit compact probe heads and tight work envelopes.
• Stem Material: Tungsten carbide stem for exceptional rigidity and long-term dimensional stability.
• Design: Straight configuration with a stepped reinforced body; supports single or multi-stepped stem arrangements.
• Tip: Ruby ball tip available in Ø0.2 mm to Ø1.0 mm for precise, wear-resistant contact geometry.
• Customization: Other dimensions can be requested via the configurator or by e-mail to tailor to specific inspection needs.

This stylus delivers reliable, high-clarity contact data by pairing a stiff carbide stem with a consistent ruby ball tip. The result is reduced deflection under load, stable measurements across multiple passes, and wear-resistant performance ideal for delicate surface probing and micro-dimension checks. The ability to select different ruby-ball diameters expands its use across various surface textures and feature sizes, making it a versatile choice for precision metrology workflows. For teams needing a tailored solution, the configurator and direct email support provide quick access to dimensions that align with your exact inspection scenario.
