The ITP Star Styli with a silicon nitride ball is a precision probing accessory designed for CMMs and measurement systems. Built for measuring large-diameter features, undercuts, and threads, it delivers rigid, repeatable performance across long gauging lengths.

• Model code: SCM3S3005020/90° — a 90-degree star configuration engineered for versatile access to challenging features.
• Ball material: Silicon nitride ball chosen for exceptional hardness, wear resistance, and smooth contact with workpieces.
• Thread compatibility: M3 XXT thread for secure, repeatable attachment to compatible probes and extensions.
• Measuring length: 11 mm measuring length to reach deep cavities and large-diameter features without bending the stem.
• Orientation: 90° stem orientation to access bottom holes, undercuts, and threaded sections from convenient angles.
• Arm design: Fixed probe arms provide stable, repeatable measurements and straightforward programming of tasks that require specific probe geometry.

This star stylus excels in applications where large diameters must be measured with minimal deflection, or where features reside in hard-to-reach areas. The combination of a silicon nitride ball, a compact M3 XXT thread, and a 11 mm measuring length enables accurate assessments of undercuts and threads, while the 90° orientation expands access to tight pockets and bottom-hole features. It’s an ideal choice for engineers who need dependable, task-specific probing that reduces setup time and improves measurement repeatability across complex parts.
