Description

The ITP Straight Styli — Type S with Ruby Ball is a straight stylus with no thread, offering a high degree of flexibility for probing in tight fixtures. Built around a tungsten carbide stem, it accepts a range of ruby ball sizes and works with standard clamp holders for seamless integration into your CMM workflow.

  • No-thread design: Straight, threadless construction for easy positioning and compatibility with common clamp holders.
  • Tungsten carbide stem: Delivers excellent stiffness and wear resistance for durable, repeatable measurements.
  • Ball size options: Ruby balls from Ø1.35 mm to Ø10.0 mm; other sizes can be requested via the configurator or by e-mail.
  • Stem configuration: Available in single- or multi-stepped forms to match diverse probing geometries.
  • Overall length: 27.5 mm, providing a compact reach for constrained measurement tasks.
  • Product code: KTM502515027
  • Clamp compatibility: Designed to be used with the appropriate clamp holder for secure, repeatable measurements.

This combination of a flexible, threadless design and a wear-resistant tungsten carbide stem makes it well suited for detailing small features, edges, and curved surfaces. The ruby ball offers precise contact points that help maintain measurement integrity across a variety of materials, while the option to customize ball size lets you tailor the stylus to your specific inspection scenarios and fixture constraints.
