ITP Straight Styli – Type A with Ruby Ball is a precision probing stylus designed for professionals who rely on consistent contact points and rigid performance in metrology, micro-assembly, and electronics inspection. Its carbide stem delivers exceptional rigidity, while the highest‑quality ruby ball provides durable, repeatable contact across tasks.

• Material: Carbide stem for superior rigidity and dimensional stability in demanding measurement environments.
• Ball Diameter Range: Ruby balls available from Ø0.5 mm up to Ø5.0 mm to suit fine-feature probing needs.
• Thread: M2 thread for secure attachment to compatible probes and holders.
• Overall Length: 30.75 mm total length, designed to work with common fixtures and keep clear of obstructions.
• Type: Straight stylus intended for everyday standard use with repeatable, reliable performance.
• Custom Sizes: Additional ruby-ball diameters can be requested via the configurator or by email for specialized applications.

This stylus is built to reduce deflection during contact, delivering consistent measurements and smoother operation on delicate surfaces. The ruby ball’s hardness and wear resistance help maintain a precise tip profile over time, making it well-suited for repeated probing tasks in quality control, electronics inspection, and precision assembly. If your project requires a non-standard diameter or a specific configuration, you can request the exact size through our configurator or by email to tailor the tool to your workflow.
