Description
The ITP Straight Styli – Type B with Ruby Ball is a precision probing stylus designed for everyday metrology tasks. Built for professionals who count on reliable, repeatable measurements, it combines a highly rigid tungsten carbide stem with quality ruby ball tips.
- Thread: M5 threaded connection for compatibility with standard probing systems.
- Overall length: 30.25 mm, providing a compact, versatile reach for tight workpieces.
- Stem material: Extremely rigid tungsten carbide to minimize deflection and improve measurement stability.
- Tip material: Ruby ball tips of the highest quality, available in Ø0.2 mm to Ø1.5 mm for different contact needs.
- Stem configuration: Straight styli designed for everyday standard use; capable of single‑ or multi‑stepped arrangements.
- Customization: Other sizes can be requested via the configurator or by e‑mail to fit specialized applications.
This design targets accurate, durable performance across a broad range of probing tasks. The tungsten carbide stem provides rigidity for consistent contact, while the ruby ball tips ensure smooth, wear‑resistant interaction with workpiece surfaces. The available ball sizes cover precise measurements of tiny features and larger contact areas, making the Type B an adaptable choice for routine inspection, calibration checks, or setup verification in both shop floors and research labs. Quick, reliable integration is supported by the standard M5 thread, and the option to tailor size if your application requires it helps you optimize measurement certainty and workflow efficiency.
