Description

The ITP Star Styli with silicon nitride ball ends is a precision probing solution designed for CMMs and inspection fixtures. With a 31 mm measuring length and M3 XXT thread, it’s built to reach deep features, undercuts, and threaded holes without bending.

  • Measuring Length: 31 mm provides extended reach for long gauging lengths while maintaining stiffness and accuracy.
  • Thread Connection: M3 XXT threaded shaft for secure mounting to compatible probes and fixtures.
  • End Ball Tips: silicon nitride balls on both ends offer durable, low-wear contact and balanced geometry for reliable measurements.
  • Star Stylus Design: fixed probe arms in a star configuration enable task-specific measuring programs and improved stability when measuring large diameters or undercuts.
  • Durable Construction: precision-machined steel body resists deflection and wear, supporting repeated, consistent use in demanding environments.
  • Ideal Use Scenarios: perfect for measuring large-diameter features, internal threads, and undercuts; can reach near the bottom of holes when the stem-direction probe is unavailable (W configuration).

With this Star Styli solution, you gain reliable, repeatable measurements for challenging features. The dual-ball geometry maintains contact without bending, while the 31 mm reach expands the inspection range for deep bores. The M3 XXT thread ensures quick, secure integration with standard probing setups, and the star-arm design supports task-specific programs that streamline setup and increase inspection throughput. Built to endure repeated use in manufacturing environments, this stylus helps you achieve precise results across parts with undercuts, threads, and bottom-hole features.
