The ITP Straight Stylus with Ruby Ball is a precision probing accessory designed for clamping star styli and expanding Z-axis measurement options in CNC and CMM workflows. It features a 103 mm overall length with an extended M4 thread to match the height of the star stylus for consistent, repeatable contact.

• Thread size and length: M4 thread with an extended shank to align perfectly with star stylus assemblies
• Overall length: 103 mm, providing reliable reach in tight probing setups
• Straight shaft design: Pure, rigid geometry for stable engagement during probing
• Height-matching extension: Extended thread ensures the stylus seats at the correct height relative to the star stylus
• Ruby ball option: Ruby probing elements available for hard, wear-resistant contact
• Compatibility: Ideal for use with star styli and standard probing rigs in CNC/CMM environments
• Construction: Precision-machined metal body for durable, consistent performance

When paired with star styli, this straight stylus enables precise Z-direction probing, supporting accurate tool setting, workpiece alignment, and dimension checks. The extended thread and exact 103 mm length help maintain consistent contact heights, reducing setup time and measurement variability. Ruby balls offer a hard, long-wearing contact surface, enhancing repeatability in high-use inspection fixtures and demanding manufacturing environments.
