ITP Star Styli deliver a robust, versatile probing solution for large-diameter features. This model combines a silicon nitride ball with a precise M3 XXT thread and a 31 mm measuring length, making it ideal for measuring deep holes, undercuts, and threaded features with reliability.

• Ball material: Silicon nitride ball for exceptional hardness, wear resistance, and consistent contact under repeated use.
• Thread: M3 XXT thread for secure, compatible mounting in your metrology setup.
• Measuring length: 31 mm gauging length designed to reach deep features without excessive probe deflection.
• Star stylus design: Proven geometry that minimizes bending when measuring large diameters or long gauging paths, with a wide range of fixed probe arms for task-specific programs.
• Applications: Particularly effective for undercuts and threads, enabling precise measurements in challenging features; supports measurements near the bottom of holes when a stem-direction probe isn’t available (typical use case: type W).

Star Styli like this one empower accurate, repeatable measurements across demanding geometries. The combination of a durable silicon nitride ball, secure M3 XXT threading, and a 31 mm measuring length helps you tackle deep recesses, thread profiles, and wide-diameter features with confidence. Its fixed-arm configurations support tailored measurement programs, reducing setup time and improving consistency across parts and batches.
