The ITP Straight Styli Type A with silicon nitride ball is a precision probing stylus built for metrology professionals and routine scanning tasks. With a carbide stem for exceptional rigidity and a standard M2 thread, it integrates smoothly with common probe heads while delivering reliable, repeatable measurements.

  • Tip material: Silicon nitride ball provides wear resistance and smooth contact, particularly advantageous for scanning untreated aluminium surfaces.
  • Stem material & rigidity: Carbide stem offers outstanding rigidity to minimize deflection during probing and improve data stability.
  • Thread: M2 thread size ensures secure mounting to compatible probe heads and fixtures.
  • Overall length: 41.5 mm total length for enhanced reach in tight or recessed measurement areas.
  • Ball size availability: In this product line, styli with balls from Ø1.0 mm to Ø5.0 mm are available; other sizes can be requested via the configurator or by email.

Designed for everyday standard use, this straight stylus enables precise contact across a variety of parts and surfaces. The silicon nitride ball maintains accuracy over time, while the rigid carbide stem supports stable measurements even in demanding scanning tasks. Its compact length and threaded compatibility make it a practical, drop-in option for many metrology setups, with easy customization available if you need a different ball diameter within the supported range.

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.
