Description

The ITP Straight Stylus Type A with Ruby Ball is a precision probing accessory designed for everyday measurement tasks. Its rigid carbide stem and high-quality ruby ball deliver reliable, repeatable contact in a compact, easy-to-use form factor.

  • Thread: M5 thread for secure mounting on compatible probing systems.
  • Overall length: 58 mm from the probing tip to the end of the stem.
  • Stem material: Carbide for exceptional rigidity and dimensional stability during use.
  • Ball size range: Ruby ball available in sizes from Ø2.0 mm to Ø10.0 mm (high-quality ruby balls).\nOther sizes can be requested via the configurator or by email.
  • Ball material: Ruby ball chosen for enduring wear resistance and smooth contact with workpieces.
  • Geometry: Straight design for predictable probing performance and easy alignment.

Designed to deliver consistent contact across a variety of surfaces and features, this stylus minimizes deflection and wear while preserving measurement accuracy. Its standard M5 mounting makes it compatible with a wide range of probing systems, and the option to specify alternate ruby-ball sizes ensures you can tailor reach and footprint to your specific tasks. Ideal for metrology, quality control, and precision inspection, the Type A ruby-ball stylus helps you achieve reliable results every time.
