ITP Star Styli – Type U with ruby ball tips is a precision metrology accessory designed for professionals who measure large-diameter features, deep bores, and threaded holes. Its star-shaped, four-arm configuration delivers stable, repeatable contact across long gauging lengths.

• Arm Configuration: Star-shaped with four fixed arms (Type U) for stable access to large diameters and deep features.
• Measuring Length: 9.5 mm gauging length, optimized for long reach without sacrificing accuracy.
• Thread Mount: M2 threading to fit standard probing systems and interchangeable spindles.
• Tip Material: Ruby ball tips provide durable, wear-resistant contact surfaces for repeatable measurements.
• Versatile Probing: Fixed arms enable task-specific measurement programs, including undercuts and threaded features.
• Durability: Star design minimizes bending risk during long gauging operations, supporting consistent results.
• Catalog Code: SIM202006032 for easy reference in your metrology library.

This design delivers accurate measurements of large bore diameters and deep holes with confidence, reducing the need for repositioning during inspection. The ruby ball tips resist wear and scoring, helping maintain calibration across cycles, while the four fixed arms provide a robust profile that supports reliable program generation for complex geometries. With its M2 thread compatibility, it integrates smoothly into common CMM setups, making it an efficient choice for quality control and precision manufacturing environments.
