The ITP Straight Styli Type A with Ruby Ball is a high‑precision probing solution designed for metrology professionals who need long reach without compromising accuracy. Built for detailed measurements in tight spaces, this stylus combines lightweight handling with exceptional rigidity.

• Material and construction: carbon fibre stem delivers low weight and superior rigidity for stable contact during probing.
• Tip technology: high‑quality ruby ball provides durable, wear‑resistant contact across a range of materials and surface finishes.
• Thread compatibility: M3 XXT thread ensures secure, quick attachment to standard probe holders and fixtures.
• Overall length: 58 mm length optimized for long‑reach measurements without sacrificing stiffness or control.
• Design purpose: specifically engineered for styli with extra length, maintaining precise deflection behavior during use.
• Dimensional options: other ruby ball diameters and related dimensions can be requested via the configurator or by email to fit your application.

This stylus is ideal for coordinate measuring machines (CMM) and other metrology setups where deep features, recessed pockets, or crowded assemblies demand extended reach. The combination of a carbon fibre shaft and a ruby ball minimizes moment of inertia while preserving rigidity, helping you achieve repeatable, accurate measurements even in demanding fixtures. The M3 XXT connection makes it easy to integrate with existing tooling, and the option to tailor dimensions ensures you can match the precise probing scenario you face—whether you’re inspecting tight tolerances on aerospace components, electronics housings, or automotive parts.
