Description
The ITP Straight Styli Type A with a silicon nitride ball is a precision probing stylus designed for everyday measurement tasks. Built for metrology professionals and workshop environments, it delivers reliable rigidity and consistent contact for accurate scans, especially on untreated aluminium parts.

- Overall length: 118 mm, providing extended reach while maintaining stability during measurements.
- Stem material: Carbide stem delivering exceptional rigidity across a wide range of dimensions.
- Ball material: Silicon nitride ball, selected for wear resistance and smooth contact on aluminium surfaces.
- Ball size range in the family: This product sits among styli that cover ball sizes from Ø1.5 mm to Ø10.0 mm, with options for Ø10.0 mm, Ø11.0 mm, and Ø12.0 mm holders in the group depending on the measuring system.
- Other sizes available by request: Additional ball sizes can be requested via the configurator or by e-mail to customize your setup.
- Ideal use: Silicon nitride balls are particularly recommended for scanning untreated aluminium parts to minimize wear and surface marking.
With a rigid carbide stem and a silicon nitride ball, this stylus delivers repeatable, precise probe contact across flat and contoured features. The 118 mm length enables you to reach recessed areas without sacrificing control, making it a dependable choice for routine metrology, calibration checks, and quality inspections. The M5 connection ensures quick, secure integration with your existing probes, while the ability to tailor ball sizes and holder options within the same family lets you optimize touch radii for specific features like small apertures or sharp corners. This combination of robustness, adaptability, and surface-friendly materials helps you maintain consistent measurement outcomes across production runs.
