Description
The ITP Star Styli with a ruby ball end is a precision measuring stylus designed for CMM and inspection workflows. Built to handle large diameters, undercuts, and threaded features, its 90° two-arm configuration delivers stable, accurate contact in tight spaces.
- Angle: 90° offset two-arm configuration for access in restricted features.
- Measuring Length: 21 mm from mounting hub to ball tip for extended reach.
- Ball End: Ruby ball provides durable, low-wear contact and high-contrast readings.
- Thread: M3 XXT threaded mount for quick, secure attachment to compatible probes.
- Arm Configuration: Two fixed probe arms stabilize measurements of large-diameter parts and features without bending.
- Applications: Ideal for measuring large bores, undercuts, and threaded pockets where conventional probes struggle.
This star stylus excels where long gauging lengths can lead to probe deflection. The fixed arms deliver consistent contact, while the ruby ball tip preserves accuracy over repeated use. With its 21 mm measuring length and 90° geometry, it expands your reach into features that are difficult to access with standard probes, making it a reliable choice for precision inspection in manufacturing, aerospace, automotive, and tooling environments.
