The ITP Straight Styli Type A with a Ruby Ball is a precision straight stylus built for metrology and probing tasks. Designed for professionals who need rigidity, reliability, and consistent contact in everyday measurements.

  • Overall length: 62.5 mm total length for accessible probing in tight spaces.
  • Thread: M5 male thread for quick, secure mounting to probe heads and adapters.
  • Stem material: Carbide for exceptional rigidity and dimensional stability during measurement.
  • Ball end: Ruby ball available in high-quality sizes, from 1.5 mm up to 8.0 mm, with additional sizes obtainable on request.
  • Finish: Polished, durable steel/stainless‑style appearance to resist wear in regular use.
  • Customization: Other ball diameters can be requested via the configurator or by email.

This straight stylus combines a rigid carbide shaft with a hard ruby ball to deliver precise, repeatable contact across a range of surfaces. The M5 threading ensures compatibility with common probing systems, while the 62.5 mm length provides reach in constrained fixtures. Ideal for CMM touch-probe workflows, surface scanning, and routine dimensional checks on metal, plastic, and composite parts. Choose the ruby ball diameter that best suits your measurement needs, and easily tailor the tool through the configurator or direct email instructions for non-standard sizes.

Buying experience
Phone requests are handled quickly and without any fuss. The website is easy to use and straightforward to order from. It’s especially helpful that it shows real‑time availability, so we don’t need to call to confirm whether parts will arrive.
