ITP Star Styli with Ruby Ball ends deliver a robust, long-reach probing solution designed for measuring large bore diameters, undercuts, and threaded features with confidence. Built for metrology teams that need dependable contact over extended gauging lengths, this model provides precise, repeatable results in challenging geometries.

• End style: Ruby ball tips on both ends for durable, high-precision contact with minimal wear.
• Measuring length: 31 mm gauging length to reach deep features without sacrificing stiffness.
• Thread: M3 XXT thread on the stem, enabling quick mounting and seamless integration with compatible fixtures and probes.
• Orientation: 180° capability for flexible probing angles and access around complex geometries.
• Star styli design: Multiple fixed probe arms allow task-specific measuring programs, ideal for handling large diameters, undercuts, and threads.
• Durability: Sturdy shank and precision construction reduce deflection and enhance repeatability during long gauging lengths.

This star-style probe excels in environments where accuracy matters over longer spans. Use it to streamline bore measurements, verify threaded features, and perform undercut inspections with a single, repeatable setup. The ruby ball tips stand up to repeated contact, while the fixed-arm configuration supports consistent, program-driven measurements across diverse parts. Its 31 mm length and M3 XXT threading provide a practical balance between reach and compatibility, making it a reliable choice for quality control workflows that require versatility without compromising precision.
