The ITP Straight Styli Type A with a ruby contact ball is a precision probing stylus designed for everyday metrology tasks. Built for reliability, it combines a rigid carbide stem with high-grade ruby contact points to deliver consistent readings across a range of measurement needs.

• Ruby ball sizes: High-quality ruby contact balls from Ø1.5 mm up to Ø8.0 mm provide clean, repeatable touch points for accurate surface probing.
• Carbide stem: Extremely rigid shaft minimizes deflection, supporting stable measurements even on challenging features.
• Thread and length: M5 thread with an overall length of 92.75 mm to fit standard probing systems and accessories.
• Product code: THM503512091 for easy ordering and support.
• Custom sizes: Other ruby-ball sizes available on request via configurator or email.

By combining stiffness with a tiny, durable ruby contact ball, this stylus reduces measurement variance and increases repeatability across scans and touch measurements. Its long reach and standard M5 thread simplify setup in routine inspection workflows, whether you’re probing flat surfaces, edges, or features with tight radii. Ideal for CMM calibration, fixture validation, and ongoing quality control, it helps you achieve reliable dimensional data with minimal wear on both the stylus and the workpiece.
