Meet the ITP Straight Styli Type A with Ruby Ball—a high‑precision probing stylus designed for measurement professionals who need long reach without sacrificing rigidity. With a 55 mm overall length and a lightweight, ultra‑rigid profile, it excels in demanding CMM and inspection tasks.

• Overall length: 55 mm total length optimized for long‑reach probing in tight or recessed features.
• Thread: M5 thread at the connection for secure, compatible mounting in probing systems.
• Stem material: Carbon fiber stem delivering exceptional rigidity while keeping weight low to reduce inertia during scans.
• Contact ball: High‑quality ruby ball for precise, durable contact; available in diameters from Ø3,0mm to Ø12,0mm.
• Weight and rigidity: Low‑weight design paired with extreme stiffness to improve stability and repeatability.
• Customization: Other dimensions can be requested via the configurator or by email to tailor reach and balance to your setup.

Designed to improve measurement confidence, this stylus minimizes deflection during rapid probe movements and delivers consistent contact geometry across cycles. The ruby ball provides a hard, wear‑resistant touch point ideal for hard materials and fine features, while the carbon fiber stem keeps the assembly responsive and easy to handle. Perfect for aerospace, automotive, mold inspection, and other precision workflows where reach, balance, and accuracy matter, with the flexibility to adjust dimensions to your exact inspection scenario.
