Description
The ITP Straight Styli Type B with Ruby Ball is a precision measuring accessory designed for everyday metrology tasks. Built for reliability, it combines a rigid tungsten carbide stem with high-quality ruby contact balls to deliver consistent, repeatable measurements on CMMs and probe systems.
- Stem material: Tungsten carbide provides exceptional rigidity and minimal deflection for accurate results.
- Ball size range: Ruby balls available from Ø0.2 mm up to Ø1.5 mm for precise contact on tiny features or larger surfaces.
- Stem configuration: Single- or multi-stepped stems to suit different measurement approaches and access requirements.
- Thread compatibility: M5 thread ensures broad compatibility with standard probe heads and adapters.
- Overall length: 75.15 mm, offering stable handling and reach in tight spaces.
- Customization: Other ruby ball sizes can be requested via the configurator or by e-mail to tailor to your application.
Whether you’re checking micro-features or validating larger surfaces, this straight stylus delivers dependable contact and long-term stability. The rigid tungsten carbide stem minimizes bending under load, reducing measurement drift, while the ruby ball provides wear-resistant, low-friction interaction with workpieces. Type B’s straightforward mounting and repeatable performance make it well-suited for standard daily metrology tasks, with easy customization if you need a non-standard ball diameter for specific parts.
