ITP Straight Styli Type B with Ruby Ball is a precision probing stylus designed for metrology professionals who rely on consistent, contact-based measurements. Built for daily use in coordinate measuring machines and inspection setups, it combines rugged construction with versatile ruby-ball tips for dependable readings.

• Stem material and rigidity: Extremely rigid tungsten carbide stem delivers high stiffness and minimal deflection across a wide range of measurements.
• Ruby-ball tip sizes: Premium ruby spheres from Ø0.2 mm to Ø1.5 mm provide precise, durable contact with surfaces and features.
• Tip size options: Other sizes can be requested via the configurator or by email to tailor the stylus to your specific tasks.
• Mounting thread: M5 thread ensures secure attachment to standard probing heads and compatible systems.
• Overall length: 20 mm overall length offers a compact reach for tight fixtures and instrument housings.
• Stem configuration: Straight design that can be configured as single- or multi-stepped to suit different probing strategies.

The combination of a durable tungsten carbide stem and high-quality ruby balls translates into repeatable, long-lasting measurements. The 20 mm length and M5 mounting make it a practical choice for routine inspection tasks, delicate feature probing, and edge or datum measurements in busy quality labs. By selecting the appropriate ruby-ball diameter (0.2–1.5 mm) or requesting a custom size, you can optimize contact geometry for your specific workpiece and measurement setup. For best results, keep the ball surfaces clean and intact, apply steady contact pressure, and recalibrate after changing ball size or configuration.
