ITP Star Styli Type U with Ruby Ball (Model WTM502015045) is a precision probing accessory designed for metrology professionals who measure large diameters, deep bores, undercuts, and threaded features. Its Type U configuration and ruby ball tips provide stable contact over long gauging lengths, helping you achieve reliable results without flex or deflection.

• Thread: M5 mounting thread for compatibility with standard probes and holders
• Measuring length: 7.5 mm measuring length to reach axial sections in deep features
• Tip: Ruby ball tips on fixed arms deliver durable, repeatable contact
• Configuration: Star stylus with Type U stem geometry for versatile measurement access
• Applications: Ideal for measuring large diameters, undercuts, and threads without bending
• Construction: Robust metal body with fixed probe arms designed for repeatable setups

This star stylus empowers precise measurements in challenging geometries. The combination of a long gauging length and a rigid star configuration minimizes deflection, making it well-suited for deep holes and long fixtures. Ruby ball tips reduce wear and maintain consistent contact across repeated cycles, supporting accurate, repeatable results. With fixed arms that support task-specific measuring programs, you can streamline setup and improve measurement consistency. When stem-direction probing is unavailable (type W scenarios), you can still obtain measurements close to the bottom of the hole, expanding your measurement options and reducing workflow bottlenecks.
