ITP Straight Styli – Type A with Ruby Ball, M3 thread, and a 21.75 mm overall length (THM3015R4022). This straight stylus is designed for everyday metrology use, delivering reliable, repeatable contact in probing workflows.

• Material: Carbide stem for exceptional rigidity and dimensional stability during probing.
• Ball: High-quality Ruby ball (Ø0.5 mm to Ø6.0 mm) provides a smooth, durable contact surface.
• Thread: M3 thread compatibility with standard probing interfaces.
• Length: 21.75 mm overall length for compact access in tight measurement envelopes.
• Design: Straight stylus geometry optimized for consistent contact and repeatable measurements.
• Customization: Additional ruby-ball sizes available by configurator or email to suit different probing strategies.

The carbide core minimizes deflection, helping you achieve stable tip geometry across a wide range of dimensions. The ruby ball combines wear resistance with smooth interaction against test surfaces, supporting accurate measurements over time. With configurable ball sizes, you can tailor the stylus to specific probing tasks, improving efficiency and reducing downtime in your inspection or calibration workflows.
