Description

The ITP Straight Styli - Type A with a Ruby Ball is a precision measuring stylus built for reliable everyday metrology. Designed for engineers and quality teams, it delivers stable, repeatable contact across a range of inspection tasks.

  • Overall length: 54 mm with a secure M5 thread for easy mounting on compatible probes.
  • Stem material: Carbide for exceptional rigidity and long-term dimensional stability.
  • Tip material: High-quality ruby ball for consistent contact and reduced wear.
  • Ball diameter range: Available in ruby balls from Ø2.0 mm to Ø10.0 mm to match feature size and measurement needs.
  • Customization: Other sizes can be requested via the configurator or by e-mail.

With its rigid carbide core and durable ruby contact, this stylus minimizes deflection under load, helping you achieve tighter tolerances and more repeatable results in CMM and profilometry tasks. The standardized 54 mm length and M5 threading simplify integration into existing inspection setups, while the range of ruby ball sizes lets you tailor the touch geometry to small features or larger datum points. For teams seeking consistent performance and easy customization, this stylus offers dependable durability and precise, predictable behavior over time.
