The ITP Straight Stylus Type T with Ruby Ball is a non-threaded probing tip designed for metrology professionals who need flexibility and reliable contact in tight spaces. With a tungsten carbide stem and a ruby ball end, it delivers precise, repeatable measurements in demanding CMM applications. This version offers a 37.5 mm overall length for extended reach.

  • Type: Straight stylus, Type T, non-threaded design for quick changes with compatible clamp holders
  • Ball tip: Ruby ball, available in sizes Ø0.2 mm to Ø5.0 mm
  • Stem material: Tungsten carbide for stiffness, wear resistance, and long-term stability
  • Overall length: 37.5 mm
  • Reach: 12.5 mm to cover probing in constrained features
  • Shank: 4 mm
  • Compatibility: Designed for use with appropriate star-stylus clamp systems
  • Part number: KTM505004037
  • Customization: Other ruby-ball sizes available on request via configurator or by e-mail

This straight stylus is ideal for CMM probing workflows where a robust, non-threaded tip is favored for quick swaps and flexible positioning. The ruby ball end minimizes wear and provides consistent contact with the workpiece, while the carbide stem maintains rigidity during scanning. Use it to access recessed features, align measurements along the Z-axis, and tailor the tip size to your geometry—without changing the overall probing setup.
