Description
The ITP Straight Styli Type A with Ruby Ball is a precision probing stylus designed for metrology professionals who need a lightweight, ultra-rigid extension for long-reach measurements. Built for high-accuracy CMM work and meticulous inspection tasks, it delivers reliable contact with small features and recessed surfaces.
- Material & Construction: Carbon fiber stem combines very low weight with exceptional rigidity for stable, repeatable measurements even on longer stylus extensions.
- Ball End: High-quality ruby ball rated from Ø3.0 mm to Ø12.0 mm provides durable, wear-resistant contact for precise data capture.
- Thread: M3 XXT threading ensures secure mounting to standard probing systems for quick, reliable setup.
- Length: 40 mm overall length offers extended reach without sacrificing control or accuracy.
- Customization: Other ruby-ball sizes or dimensions can be requested via the configurator or by e-mail to tailor the stylus to your application.
Designed to minimize inertia and deflection, this stylus helps you maintain high-resolution readings across challenging geometries. The ruby ball’s hardness and smooth contact reduce wear over many cycles, while the carbon fiber body dampens vibrations for steadier data collection. Ideal for metrology labs, manufacturing QC, and precision engineers, it enables reliable measurements of tiny features, deep pockets, and tight tolerances, making your inspection workflow more efficient and consistent.
