The ITP Star Styli with a ruby ball tip are precision probing accessories designed for CMM workflows that demand reliable, long-reach measurements. Built to handle large diameters, undercuts, and threaded features, this stylus maintains rigidity and accuracy even with extended gauging lengths.

• Tip material: Ruby ball provides exceptional wear resistance and repeatable contact for high-precision measurements.
• Thread: M3 XXT threaded connection ensures secure attachment to compatible probe heads and fixtures.
• Measuring length: 31 mm measuring length enables deep-feature probing without compromising stiffness or deflection control.
• Star stylus design: Fixed probe arms and star geometry reduce bending risk and maintain stable contact on challenging surfaces.
• Application: Ideal for measuring large-diameter features, undercuts, thread geometry, and bottom-of-hole areas in QA and calibration workflows.
• Configuration flexibility: Designed to support task-specific measuring programs and varied inspection setups with reliable repeatability.

In practical use, this ruby-ball star stylus delivers consistent geometry for critical measurements, helping you achieve repeatable results across repeated runs and different parts. The combination of a robust 31 mm length, durable ruby contact, and secure M3 XXT attachment minimizes measurement variability and reduces setup time in busy inspection environments. Whether you’re gauging deep holes, examining thread forms, or profiling large-diameter features, this stylus provides dependable performance and long-term durability for everyday CMM tasks.
