The ITP Straight Styli Type A with Ruby Ball delivers a lightweight, ultra-rigid probing solution designed for long-reach measurements in CMM and inspection setups. Built for metrology professionals who demand precision without added mass, it combines a carbon fiber stem with a high-quality ruby ball for dependable, repeatable probing.

• Overall Length: 104 mm for extended reach into tight features and deep pockets.
• Thread: M5 threading for secure attachment to compatible probes.
• Stem Material: Carbon fiber for very low weight and exceptional rigidity, minimizing deflection during contact.
• Tip Material: Ruby ball ensuring hard-wearing, precise contact with surface features.
• Tip Diameter Options: Available with ruby balls from Ø3.0 mm up to Ø12.0 mm to suit different measurement needs.
• Custom Dimensions: Other dimensions can be requested via the configurator or by email.

With its ultra-light carbon fiber core, this stylus minimizes inertial effects during scanning, boosting responsiveness and measurement repeatability. The ruby ball provides a smooth, durable contact surface that resists wear, while the 104 mm reach enables probing into recessed features without sacrificing stability. This makes the Type A ruby-ball stylus ideal for precision manufacturing, aerospace, automotive, and medical device inspection tasks where consistency and accuracy across multiple parts matter.
