Description

ITP Straight Styli Type A with a ruby ball offers a reliable probing solution for everyday metrology tasks. Designed for technicians and quality teams, its rigid carbide stem and precision ruby tip provide consistent, repeatable measurements across a range of applications.

  • 100 mm overall length: generous reach for probing larger parts or accessing recessed features without sacrificing accuracy.
  • M5 thread: standard mounting interface for quick, secure integration with compatible probes and fixtures.
  • Rigid carbide stem: exceptional stiffness minimizes deflection and maintains dimensional stability during use.
  • Ruby ball tip: high-quality ruby contact surface delivers smooth, wear-resistant performance with repeatable results; diameters range from Ø2.0 mm to Ø10.0 mm.
  • Custom sizing on request: other ruby ball diameters can be requested via configurator or by e-mail to tailor the stylus to your measurement range.

With this stylus, you gain a durable, precise touch point that helps reduce measurement variability and extend tool life. The carbide’s rigidity combined with a ruby ball ensures reliable contact across repeated cycles, making it well-suited for CMM workflows, fixture-based inspections, and manual probing on a variety of parts. The 100 mm length covers a broad range of applications, while the M5 thread ensures compatibility with many standard probing systems. If your process requires a specific touch-point diameter, you can request the exact ruby ball size to optimize accuracy and consistency in your measurements.
