The ITP Straight Styli - Type B with Ruby Ball is a precision straight stylus designed for everyday metrology tasks. It combines a rigid tungsten carbide stem with small ruby ball tips to deliver repeatable, reliable contact in tight measurement scenarios.

  • Material and construction: Very rigid tungsten carbide stem provides long-term rigidity and durability for accurate probing.
  • Tip type: High-quality ruby ball tips available from Ø0.3 mm to Ø1.0 mm for precise contact and minimal wear on workpieces.
  • Geometry: Straight stem with support for single or multi-stepped configurations to suit different probing needs.
  • Thread: M3 XXT thread for secure mounting in compatible probes and holders.
  • Dimensions: 24 mm overall length, offering a compact footprint for crowded measurement setups.
  • Custom sizing: Other sizes can be requested via the configurator or by e-mail to tailor the stylus to your fixture or feature size.

Designed to enhance accuracy across repeated measurements, this stylus minimizes deflection and wear while delivering consistent tactile feedback. The ruby ball tip protects delicate surfaces and maintains surface finishes, while the tungsten carbide stem preserves straightness under probing loads. With versatile sizing options and easy customization, it’s well suited for a wide range of metrology tasks and measurement fixtures.
