Description
ITP Straight Styli Type A with a ruby ball offers reliable, precise probing for everyday measurement tasks. Built for professionals who demand consistent contact measurements, it combines a rigid carbide stem with high‑quality ruby ball tips.
- Thread: M5 thread for secure mounting on standard probe assemblies.
- Overall length: 36.5 mm, providing a balanced reach for typical probing scenarios.
- Stem material: Carbide stem delivering exceptional rigidity and dimensional stability under use.
- Tip material: Ruby ball tips (high-quality) to minimize wear and ensure smooth contact with measured surfaces.
- Tip diameter range: Standard ruby balls from Ø1.5 mm up to Ø8.0 mm, suitable for a wide range of features; other sizes can be requested via the configurator or by email.
- Design: Straight stylus intended for everyday standard use, offering predictable probing geometry and easy handling.
This stylus is designed to deliver repeatable, accurate measurements across CMM touch probes and other measurement setups. The rigid carbide shaft reduces deflection during contact, while the ruby ball provides durable wear resistance for long‑term use. With a practical 36.5 mm length and a secure M5 mount, it’s well suited for inspecting fine features, flat surfaces, and small radii. The option to request alternative ruby-ball sizes via the configurator or by email gives you flexibility to tailor the tip to your specific measurement needs, helping improve data quality and consistency over time.
