Description
The ITP Straight Styli Type B with Ruby Ball is a precision probing stylus designed for metrology and inspection workflows. Built for everyday standard use, it delivers consistent, repeatable contact thanks to a highly rigid tungsten carbide stem and high-quality ruby contact balls.
- Material and stem: Extremely rigid tungsten carbide stem offers excellent dimensional stability and supports both single- and multi-stepped configurations for varied probing needs.
- Ruby ball sizes: High-quality ruby balls available in Ø0.2 mm to Ø1.5 mm to suit different contact areas and measurement resolutions.
- Thread and length: M5 threaded connection with an overall length of 22.1 mm for reliable fit in standard holders and probing setups.
- Geometry: Straight stylus design provides straightforward, repeatable contact for everyday metrology tasks.
- Custom sizing: Other sizes can be requested via the configurator or by e-mail to tailor the stylus to specific applications.
- Product identifier: NHM500611022 for easy ordering and reference.
This combination of a rigid carbide stem, high-grade ruby balls, and a precise M5 thread makes the Type B ruby-ball stylus ideal for CMM probing, precision measurement, and delicate surface contact. The ability to choose different ruby-ball diameters lets you balance contact area against measurement sensitivity, while the sturdy construction supports long-term use in demanding environments. Use cases include routine QC checks, fixture inspection, and repeatable probing across a range of feature sizes.
