Description

The ITP Star Styli Type W with Ruby Ball is a precision measuring probe designed for gauging large-diameter features and deep bores. It's ideal for metrology professionals who need stable contact for challenging internal geometries, including undercuts and threads, without risking probe bending.

  • M2 Thread x 7.75mm Measuring Length: Compact, standard interface with a defined 7.75 mm measuring reach for quick setup and reliable readings.
  • Ruby Ball Tips: Fixed ruby ball contact points deliver consistent, repeatable measurements with excellent wear resistance.
  • Type W Configuration: No probe in the stem direction, enabling measurements very close to the bottom of holes when a stem probe isn’t used.
  • Star-Style Fixed Arm Set: Multiple fixed probe arms arranged in a star pattern to cover large diameters and support task-specific measuring programs.
  • Undercuts and Threads Ready: Specifically suitable for capturing features like undercuts and threaded recesses in a single setup.
  • Product Code: SIM200505020

By using the Star Styli Type W, you gain stable contact across long gauging lengths, reducing deflection and improving repeatability on large-diameter inspections. The star-arm configuration provides versatile coverage for internal features, while the lack of a stem probe in this variant lets you approach hole bottoms more closely. Ruby ball tips minimize wear and maintain consistent readings over multiple parts, and the M2 threading ensures quick integration with common metrology accessories, streamlining your inspection workflow.
