Description
The ITP Straight Styli Type B with Ruby Ball is a precision probing stylus designed for machinists and metrology professionals who need reliable, repeatable measurements in everyday use. Built around a rigid carbide stem and a high-quality ruby contact ball, it delivers consistent contact across small features and tight tolerances.
- Stem material: Carbide stem for exceptional rigidity and minimal deflection during probing.
- Tip: Ruby ball contact points from Ø0.2 mm to Ø1.0 mm provide durable, precise contact.
- Thread: M2 threading to fit standard probing heads and interfaces.
- Overall length: 18 mm for a compact, versatile probing profile.
- Stem configuration: Available as single- or multi-stepped stems to suit different probe geometries.
- Form factor: Type B design within the ITP styli lineup for consistent compatibility.
- Custom sizes: Additional ruby-ball diameters available on request via configurator or by e-mail.
This stylus is ideal for tool setting, fixture verification, and part-to-CAD alignment in machining environments. The carbide stem minimizes bending under load, helping you achieve repeatable touchpoints, while the ruby ball’s hardness and smooth contact reduce wear over many cycles. Its compact 18 mm length and M2 thread simplify integration with existing probing systems, and the option to tailor the ruby-ball size ensures you can match feature sizes precisely. For needs beyond the listed diameters, additional sizes can be requested to fit your specific measurement tasks.
