Description
ITP Straight Styli – Type B with a ruby ball is a precision probing stylus designed for everyday metrology and inspection tasks. Built for engineers and technicians who need reliable, repeatable tactile measurements, this straight stylus delivers consistent contact and long-term durability.
- Stem material: Extremely rigid tungsten carbide center provides high stiffness and wear resistance for stable probing across many measurements.
- Tip material and sizes: High-quality ruby ball tips available in diameters from Ø0.3 mm up to Ø1.0 mm for fine-feature probing and adaptable contact areas.
- Thread: M3 XXT mounting thread for secure integration with standard probe heads and fixtures.
- Overall length: 20 mm overall length offers compatibility with common probing configurations and measurement setups.
- Stem configuration: Can be configured as either a single-step or multi-stepped stem to suit different measurement strategies.
- Customization: Additional sizes can be requested via the configurator or by e‑mail to match your specific instrument or application.
This stylus is ideal for precision work in coordinate measuring machines, optical inspection, and micro-manufacturing environments where a rigid stem and a hard ruby contact point help achieve accurate, repeatable results. The ruby ball’s hardness minimizes wear and maintains consistent contact geometry over many cycles, while the carbide stem resists bending under typical probing loads. If you need a non-standard size, simply request a custom option to fit your measuring system without compromising accuracy.
