Meet the ITP Straight Stylus Type A with Ruby Ball — Model THM502011025 — a precision probing tool designed for CMMs and tactile inspection tasks. Built for professionals who demand reliability in everyday measurements, it combines a rigid carbide stem with a high-quality ruby ball for consistent contact.

• Thread: M5 male thread for secure mounting on standard probe heads
• Overall length: 25 mm for compact, versatile use in tight measurement setups
• Stem material: Carbide stem delivers exceptional rigidity and minimizes bending under probing loads
• Tip: Ruby ball provides hard, wear-resistant contact; ruby ball sizes range Ø2.0 mm to Ø10.0 mm, with custom options available via configurator or by email

Designed to minimize deflection and maximize repeatability, this stylus helps you achieve consistent readings across sessions. The ruby ball's hardness reduces wear and maintains contact accuracy, while the compact 25 mm length fits into crowded fixtures and probe heads. Ideal for measuring small features such as shallow pockets, tight holes, and edge radii, as well as routine calibration tasks. If you need a different ball size, custom options can be requested through the configurator or by email.
