Description
The ITP Straight Styli - Type A with Ruby Ball is a precision probing stylus designed for everyday measurement tasks in metrology labs and manufacturing environments. It pairs a rigid carbide stem with a titanium Ø5.0 mm holder and a high-quality ruby ball for dependable, repeatable contact data.
- Overall length: 20 mm total length for compatibility with common probing systems.
- Thread: M3 XXT thread for secure, reliable mounting.
- Holder material: Titanium Ø5.0 mm holder offering light weight, strength, and corrosion resistance.
- Stem material: Carbide stem delivering high rigidity and dimensional stability.
- Ruby ball sizing: High-quality ruby ball used for precise contact, available from Ø0.8 mm to Ø2.5 mm.
- Customization: Additional ruby ball sizes can be requested via the configurator or by email.
With its combination of carbide rigidity and a stable ruby contact, this stylus minimizes deflection under load to deliver consistent measurements across a range of features, from fine details to smooth surfaces. The compact 20 mm length keeps the stylus unobtrusive in tight fixtures, while the titanium holder provides durability without adding unnecessary weight. This makes the Type A ideal for routine inspection tasks, calibration runs, and precise alignment in busy production environments. If you need a different contact sphere, you can easily adjust the ruby ball size through the configurator or by contacting support for a tailored option.
