Description

The ITP Straight Styli Type A with Ruby Ball is a precision stylus built for everyday metrology tasks. Designed for engineers and quality inspectors, it pairs a rigid carbide stem with a high-quality ruby ball to deliver consistent, reliable touchpoints in CMM setups.

  • Product Code: THM405007052
  • Ball Diameter Range: Ruby balls from Ø1.0 mm to Ø6.0 mm are used to cover a wide range of feature sizes.
  • Material & Construction: Carbide stem provides exceptional rigidity and long-term stability for accurate measurements.
  • Thread: M4 thread for secure mounting in standard stylus holders and fixtures.
  • Overall Length: 52.5 mm from tip to base, offering a compact profile for tight measurement spaces.
  • Customization: Other sizes can be requested via the configurator or by e-mail to tailor the stylus to specific applications.

This stylus excels in delivering repeatable touchpoints, reducing deflection and wear during routine measurement tasks. The ruby ball provides durable, smooth contact with a variety of surfaces, helping you achieve cleaner data and more consistent probe trails. For specialized applications, you can request a custom ruby-ball diameter to perfectly suit your fixture or feature size.
