The ITP Straight Styli - Type A with Ruby Ball is a precision measurement stylus designed for everyday testing and inspection tasks. Built for engineers and technicians, it combines a rigid carbide stem with a lightweight titanium holder and standard M3 XXT threading for straightforward integration, all in a compact 40 mm overall length.

• Thread: M3 XXT thread for secure mounting to compatible probes and holders.
• Overall Length: 40 mm, optimized for access in tight measurement areas.
• Holder Material: Ø5.0 mm titanium holder delivers strength with minimal weight.
• Stem Construction: Carbide stem provides extreme rigidity for a wide range of dimensioning tasks.
• Ruby Ball Sizes: High-quality ruby balls available from Ø0.8 mm to Ø2.5 mm for precise contact geometry.
• Customization: Additional ruby ball sizes can be requested via configurator or by email.

Designed to minimize deflection and wear while delivering repeatable touch-down measurements, this stylus is ideal for probing delicate features, small pockets, or tight-feature inspection. The combination of a titanium holder and a carbide stem ensures durable performance across routine metrology work, while the ruby ball’s hardness provides long-lasting, accurate contact. If your application requires a different ball diameter, you can request the exact size you need through the configurator or by email to tailor the stylus to your measurement workflow.
