Description

ITP Star Styli Type U with Ruby Ball tips offers a robust, multi-arm probing solution designed for measuring large diameters, undercuts, and threaded features. Built for metrology professionals using CMMs and shop-floor inspection, this 8 mm measuring length star stylus delivers stable contact across long gauging paths.

  • Configuration: Type U with four fixed probe arms for stable, multi-directional contact along long gauging lengths.
  • Tips: Ruby ball tips on all probes provide wear-resistant, consistent contact for accurate readings.
  • Measuring Length: 8 mm measuring length to reach deep features without bending the stylus.
  • Mounting: M5 mounting thread for quick, secure integration with standard measurement heads and fixtures.
  • Primary Applications: Ideal for measuring large diameters, undercuts, and threaded features in a single probing setup.
  • Durability: Fixed arms minimize deflection and maintain accuracy across extended gauging paths.

With the ITP Star Styli, you gain a dependable probing solution that protects against bending when reaching deep features, enabling repeatable measurements across long gauges. The fixed-arm design supports task-specific measuring programs, reducing setup time and improving consistency for parts with large diameters, undercuts, or threaded profiles. Ruby ball tips contribute to long‑lasting accuracy, while the 8 mm measuring length and M5 mounting thread ensure compatibility with common CMM and inspection setups, making this a practical upgrade for demanding metrology tasks.
