Description

ITP Straight Styli – Type S with Ruby Ball is a versatile, no-thread probing stylus designed for precision metrology setups. Built for technicians and inspectors who rely on fast swaps in clamp holders, it offers robust performance in tight measurement cells with dependable repeatability.

  • Stem material: Tungsten carbide stem delivers exceptional stiffness, wear resistance, and long-term accuracy in demanding probing tasks.
  • Tip geometry: Ruby ball tip available in diameters from Ø1.35 mm up to Ø10.00 mm to suit delicate surface probing and diverse part geometries.
  • No threaded shank: Straight, non-threaded design that integrates smoothly with compatible clamp holders for quick, tool-free changes.
  • Overall length: 38 mm, providing reach into confined areas while maintaining precise contact with the part under inspection.
  • Configuration options: Can be supplied as single- or multi-stepped stems; for sizes beyond the standard range, requests can be made via configurator or by email.

This ruby-ball stylus excels in applications such as scratch-free probing of sensitive surfaces, high-precision feature measurement, and rapid setup in CMM workflows. The combination of a rugged tungsten carbide shaft and a hard ruby contact point offers durable performance across repeated cycles, while the no-thread design simplifies tooling changes in busy inspection environments. Ideal for metrology professionals who value consistency, flexibility, and efficiency in everyday measurement tasks.
