The ITP Straight Styli Type A with Ruby Ball (Model TCM505010052) is a long-reach, low‑weight probe stylus designed for precise CMM probing and metrology applications. Its carbon fiber stem delivers exceptional rigidity for accurate measurements even with extended length.

• Tip option: High‑quality ruby ball tip available in diameters from Ø3.0 mm to Ø12.0 mm for stable, wear‑resistant contact with diverse workpiece surfaces.
• Stem material: Carbon fiber stem providing a light yet highly rigid shaft to minimize deflection during probing.
• Overall length: 52.5 mm total length in a straight (Type A) configuration to reach recessed features without compromising stability.
• Thread: M5 external thread for compatibility with standard probing heads and accessories.
• Specialized design: Specifically suited for styli with excess length, offering reliable performance in challenging measuring scenarios.
• Customization: Other dimensions can be requested via the configurator or by e‑mail to tailor to your measurement setup.

This combination of light weight and high rigidity helps deliver repeatable contact measurements, extended tip life, and consistent geometry across repeated cycles. The ruby ball tip provides a hard, low‑wear contact surface, while the carbon fiber body minimizes mass at the tip to reduce dynamic effects during scanning. Ideal for professionals who need a long‑reaching, precise stylus that fits standard M5 interfaces without sacrificing stability or accuracy.
