The ITP Star Styli Type W with Ruby Ball is a precision probing accessory designed for CMM and metrology workflows that require measuring large diameters, deep bores, and threaded features with minimal deflection. Its star-shaped four-arm design provides stable contact across long gauging lengths, making it ideal for challenging geometries.

• Configuration: Star stylus with Type W stem and four fixed arms arranged radially to reach around features when probing in the stem direction is limited.
• Measuring length: 14.5 mm, enabling long gauging paths without undue bending of the stem.
• Thread: M2 mounting thread for secure attachment to compatible probes and fixtures.
• Tip material: Ruby ball tips deliver durable, wear-resistant contact with consistent sizing across measurements.
• Arm count: 4 fixed probe arms for broad, stable contact on large diameters and complex features.
• Material and build: Stainless steel body for rigidity, corrosion resistance, and lasting accuracy in demanding environments.
• Part number: SIM201005021
• Best use: Measuring large bores, undercuts, threads, and other hard-to-reach features where a conventional probe can’t reach reliably.

This star stylus delivers repeatable, high-precision measurements by distributing contact forces across multiple arms, reducing deflection, and enabling measurements close to the bottom of holes when there is no probe in the stem direction. Its robust build and ruby tips help sustain accuracy over many cycles in busy manufacturing environments, making it a dependable choice for precision inspection tasks.
