ITP Straight Styli Type J Ruby Ball with M3 thread delivers a lightweight, high-rigidity probing solution for long-reach measurements in precision metrology. Designed for engineers and technicians using CMMs or inspection systems, it combines a carbon fiber stem with a wear-resistant ruby contact ball for accurate, repeatable results.

• Overall length: 106 mm
• Mounting thread: M3 threading for secure attachment
• Contact tip: Type J ruby ball available in Ø6.0 mm to Ø12.0 mm
• Stem material: Carbon fiber for low weight and high rigidity
• Designed for long-reach styli: Optimized for configurations with extended length
• Customization: Other dimensions available via configurator or by email

By pairing a lightweight carbon fiber stem with a precision ruby ball, this stylus minimizes bending and vibration while maintaining excellent durability. The ruby ball provides consistent contact geometry, improving measurement repeatability across repeated probes and scans. Its long reach enables access to recessed features and larger components without sacrificing stability. If you need different ball sizes or lengths, you can request a custom configuration through the configurator or by email to fit your exact inspection workflow.
