Description
Meet the ITP Star Styli Type U with Ruby Ball—the robust internal measuring stylus built for deep bores, large-diameter features, and hard-to-reach threads. Three fixed arms and ruby ball tips deliver stable, repeatable measurements across long gauging lengths.
- Configuration: Type U star stylus with three fixed probes arranged around the stem for balanced, multi-direction contact.
- Probe tips: Ruby ball tips provide wear resistance and consistent contact for accurate readings over many cycles.
- Threaded mounting: M5 threaded stem for secure integration with compatible measurement heads and stylus adapters.
- Measuring length: 7.5 mm measuring length enables access to deep features without excessive flex or bending.
- Primary applications: Ideal for measuring large bore diameters, undercuts, and threaded interiors where traditional slender styli struggle.
- Durability: Built to maintain precision in demanding metrology environments with a robust star-stylus design.
The three-arm Star Styli arrangement ensures rigid contact across extended gauging lengths, helping you achieve repeatable measurements with reduced deflection. Ruby ball tips resist wear, maintaining accuracy over time, while the compact M5 threaded stem makes it easy to fit into existing probing setups. Use this Type U stylus to expand your internal measurement capabilities—especially where deep access and stable contact are essential.
