Description
The ITP Straight Styli Type A with a ruby ball is a precision contact stylus designed for metrology professionals and CMM workflows. Built for everyday use, it combines robustness with fine-tuned tip options to deliver repeatable, reliable measurements.
- Thread: M3 XXT thread for secure mounting on standard probe heads
- Holder material: Titanium Ø5.0 mm holder for durability and lightweight performance
- Stem material: Carbide stem providing exceptional rigidity and minimal deflection
- Tip options: Ruby ball tips available from Ø0.8 mm up to Ø2.5 mm for different measurement needs
- Overall length: 20 mm, designed for compact reach in tight fixtures
- Size availability: Further sizes can be requested via the configurator or by e-mail
This straight stylus delivers precise contact with minimal wear, thanks to the high-quality ruby ball and the stiffness of the carbide stem. The titanium holder reduces mass while maintaining strength, helping to maintain stable tactile feedback during probing. Ideal for routine inspection tasks, fixture validation, and detailed feature measurement where consistent contact and repeatable results matter. Use it in everyday metrology scenarios, and choose the tip size that best matches the feature being measured for optimal accuracy.
