The ITP Star Styli are precision measuring probes designed to tackle challenging features with confidence. This 90° variant combines a silicon nitride ball, a compact M3 XXT thread, and a 31 mm measuring length to reach deep, hard-to-access surfaces—perfect for gauging large diameters, undercuts, and threaded features.

• Tip material: Silicon nitride ball for exceptional hardness, wear resistance, and stable contact over many cycles.
• Thread: M3 XXT threaded stem ensures secure, repeatable mounting in compatible probing systems.
• Measuring length: 31 mm length to access deep holes and extended gauging paths without bending the stem.
• Angle: 90° orientation enables measurements close to the bottom of holes and along undercuts with minimal interference.
• Design versatility: Star-style fixed probe arms provide task-specific configurations for efficient, repeatable measurement programs.
• Application versatility: Ideal for measuring large diameters, undercuts, and threaded features in complex parts and assemblies.

This star stylus delivers dependable performance in demanding metrology workflows. By minimizing bending risk on long gauging lengths and enabling precise contact at challenging geometries, it helps reduce measurement time, improve repeatability, and expand the range of features you can accurately inspect with a single probe setup.
