The ITP Straight Stylus Type A with Ruby Ball is a precision metrology accessory designed for everyday measurement tasks. Built for engineers and quality labs, it combines a lightweight ceramic stem with a hard ruby contact to deliver reliable, repeatable touch measurements.

• Tip material: Ruby ball used for precise, wear-resistant contact; available in sizes Ø4.0 mm to Ø8.0 mm (other sizes can be requested).
• Stem material: High-performance ceramic for low weight and exceptional rigidity, reducing flex during probing.
• Thread: M4 thread to fit standard probe heads and stylus holders.
• Overall length: 52 mm, offering a compact reach suitable for tight fixtures and accessible surfaces.
• Designation: Straight stylus designed for everyday, standard use in metrology workflows.
• Customization: Additional ruby ball sizes available on request via configurator or by email.

This stylus is designed to maximize measurement consistency in CMM and handheld probing scenarios. The combination of a lightweight ceramic stem and a hard ruby contact minimizes deflection and wear, helping you achieve repeatable data across multiple parts and setups. With its standard M4 threading, it integrates smoothly with existing equipment, while the option to request alternate ruby ball sizes ensures you can tailor the stylus to feature size, surface finish, and probing geometry that best suit your inspection program.
