Description

The ITP Straight Stylus Type A with a silicon nitride ball is a dependable probing solution for precision metrology. Designed for everyday standard use, it combines a rigid carbide stem with a high-performance ball to tackle a range of measurement tasks, including scanning untreated aluminium parts.

  • Thread: M5 thread for secure mounting on standard stylus holders.
  • Overall Length: 57 mm from base to tip for compact, balanced probing in tight spaces.
  • Stem Material: Extremely rigid carbide stem to maintain dimensional stability across measurements.
  • Ball Material: Silicon nitride ball, chosen for durability and wear resistance during scanning.
  • Ball Size Range: Ball sizes in this group range Ø1.5 mm to Ø10.0 mm; other sizes can be requested via the configurator or by e-mail.
  • Holder Compatibility: Suitable with Ø10.0 mm, Ø11.0 mm, and Ø12.0 mm holders depending on your measuring system.
  • Application Focus: Ideal for everyday CMM probing and scanning of untreated aluminium surfaces.

With its combination of a high-stability carbide stem and a wear-resistant silicon nitride ball, this stylus delivers repeatable contact and precise data across a broad range of dimensions. The 57 mm length plus M5 threading makes it easy to integrate into existing setups, while compatibility with multiple holder sizes expands its versatility. If you need a different ball diameter, you can tailor the selection through the configurator or by contacting support for a customized option.
