Meet the ITP Star Styli Type U with a ruby ball—designed for metrology professionals who need precise, long-reach contact in holes, threads, and undercuts. This ruby-ball star stylus delivers stable measurements across long gauging lengths with a compact, robust form.
- Type U star-stylus geometry: Four fixed probe arms radiate from a compact body to provide stable contact and minimize bending during long measurements.
- Ruby ball tips: Each arm ends in a ruby contact ball for durable wear resistance and repeatable surface interaction.
- M5 mounting thread: Features a standard M5 thread on the stem for quick, secure integration with compatible probe heads.
- Measuring length: 15 mm measuring length enables access to deep or recessed features without compromising accuracy.
- Rigid construction: Hardened steel body with precisely formed arms ensures longevity under routine CMM use.
- Type U applicability: Ideal for measuring near the bottom of holes or undercuts when no stem probe direction is available, enabling task-specific measurement programs.
This star stylus is a practical choice for measuring large diameters and threaded features with confidence. The combination of ruby-ball tips, a 15 mm reach, and a sturdy Type U design reduces probe changes, supports repeatable results, and helps you complete complex gauging tasks efficiently in a single setup.
