The ITP Straight Styli – Type A with Ruby Ball is a precision probing stylus designed for reliable, everyday measurement in metrology and quality-control workflows. Built around a carbide stem for exceptional rigidity, it delivers stable contact and repeatable results across demanding probing tasks.

• Material and construction: Carbide stem provides high rigidity and long-term dimensional stability for repeatable measurements.
• Ruby ball sizes: High-quality ruby balls available from Ø0.5 mm up to Ø5.0 mm for optimized contact depending on feature size.
• Overall length: 31 mm total length creates a compact, balanced probing geometry for precise touchpoints.
• Thread compatibility: M2 thread for easy mounting with compatible probe heads and adapters.
• Custom sizing availability: Additional sizes can be requested via the configurator or by email to suit specific measurement needs.

Ideal for CMM probing, tactile metrology, and fixture setup, this straight stylus helps you achieve cleaner data and smoother workflows. The combination of a rigid carbide stem and a precisely sized ruby ball minimizes deflection during contact, improving measurement accuracy and surface interaction. When you need to tailor probe geometry to delicate features or tight tolerances, you can request different ruby ball diameters to match your application, all while using a single, reliable tool design.
