Description

The ITP Straight Styli – Type A with a ruby ball is a precision tactile stylus designed for everyday metrology tasks. Built around a carbide stem for maximum rigidity, it delivers consistent contact and reliable measurements across a range of applications.

  • Thread: M5 thread for secure mounting on standard probing systems.
  • Overall length: 20 mm for a compact probing profile in tight spaces.
  • Stem material: Carbide stem provides exceptional rigidity and long-term dimensional stability.
  • Ruby ball range: Ruby balls from Ø2,0 mm to Ø10,0 mm enable different contact profiles for features of varying sizes.
  • Customization: Other sizes can be requested via the configurator or by e-mail to match specific measurement tasks.
  • Model/code: THM502011020 for easy ordering and reference.

By combining a rigid carbide stem with high-quality ruby balls, this straight stylus minimizes deflection under probing forces and supports repeatable measurements. The 20 mm length and M5 thread ensure compatibility with common metrology setups, while the option to tailor ruby ball size provides flexibility for delicate surfaces or small features. Ideal for routine part inspection, surface mapping, and feature verification, the ITP Straight Styli – Type A with Ruby Ball delivers dependable touchpoints that help you capture accurate, consistent data.
