The ITP Star Stylus with a silicon nitride ball is a versatile probing accessory designed for measuring large diameters, deep cavities, and threaded features with confidence. It’s ideal for metrology professionals who need long gauging lengths without bending and precise access to hard-to-reach areas.

• Ball Material: Silicon nitride ball provides high hardness, wear resistance, and smooth contact with measured surfaces.
• Thread: M3 XXT thread for secure, quick attachment to compatible stylus assemblies.
• Measuring Length: 21 mm measuring length from the mounting point to the ball tip, enabling deep gauging while maintaining rigidity.
• Angle/Orientation: 90° right-angle configuration that reaches features around holes, steps, and undercuts without interference.
• Star Stylus Design: Part of the star stylus family with multiple fixed probe arms, enabling task-specific measuring programs for varied geometries.
• Key Applications: Especially effective for measuring large diameters, undercuts, and threads; when there is no stem-direction probe (type W), you can measure close to the bottom of the hole.

This configuration minimizes bending risk on long gauging lengths while preserving accuracy, expands access to challenging features, and supports repeatable measurements across complex geometries. The silicon nitride ball provides durable contact, reducing wear over time and helping you maintain consistent results in routine inspection tasks or complex measurement scenarios.
