Description
ITP Straight Styli – Type A with a ruby ball is a precision probing stylus designed for reliable, everyday use in measurement tasks. Built for professionals employing CMMs and inspection fixtures, it combines a rigid carbide stem with a high-quality ruby ball for consistent contact and long-lasting performance.
- Thread size: M5 thread to fit a wide range of probing systems and adapters.
- Overall length: 21.25 mm from the base to the tip for compact, accessible probing.
- Stem material: Carbide stem delivering exceptional rigidity and wear resistance under repeated use.
- Tip material: Ruby ball tip, renowned for hardness and smooth contact; available in sizes from Ø0.7 mm to Ø3.0 mm.
- Ball diameters: Ø0.7 mm up to Ø3.0 mm to suit delicate surfaces or broader contact areas.

This stylus is crafted to minimize deflection and maintain stable measurements across diverse materials and finishes. The ruby ball geometry lets you tailor touchpoints for surface sensitivity or robustness, while the carbide stem endures tough inspection environments. Ideal for routine CMM probing, fixture-based measurements, and handheld inspection where repeatable, accurate contact counts.
