Description
The ITP Star Styli with a ruby ball tip is a versatile probing accessory designed for precision measurement on CMMs and handheld gauging. Ideal for metrology professionals dealing with large diameters, deep holes, undercuts, and threaded features, it delivers rigid performance without sacrificing accessibility.
- End Tip: Ruby ball tip provides durable, precise contact for accurate measurements in challenging geometries.
- Mounting Thread: M3 XXT thread for secure, compatible attachment to standard probes.
- Measuring Length: 11 mm measuring length enables deep access while preserving stiffness and stability.
- Star-Style Geometry: Fixed probe arms support task-specific measurement configurations, reducing deflection on long gauging lengths.
- Application Flexibility: Excellent for measuring large diameters, undercuts, threaded features, or locations near the bottom of holes when stem direction is limited.
This star stylus excels at expanding your measurement reach with reliability. The ruby-tipped contact sustains repeatable results across extended gauging lengths, helping you streamline setups and achieve consistent inspections across a range of parts and features.
